You know those large, illuminated maps in shopping malls, the ones bearing a big red dot with the words, YOU ARE HERE? As she does each week, Beth opened our Saturday yoga class with a parable that prefaced the morning’s lesson, employing one of those signs as a metaphor.

Typically, the theme of class ranges from softening judgement on our limitations, like how flexible we’re not, to investigating the need for sensation beyond what’s necessary, known as cranking the dial to eleven. Most often, it relates to being mentally present in our physical bodies, an uphill battle if you consider how early we’re conditioned to drift. As youngsters in school and church, we spend the majority of our childhoods distracted, gazing out windows, picturing ourselves somewhere else. As adults, we zone out in meetings as co-workers drone on about mission statements and the quarterly budget.

From television and digital devices to old-fashioned daydreaming, we live our lives in a constant undercurrent of escape — that is, until we show up for yoga class where we are reminded to be present. We pay spry bodhisattvas to center us in the same world that we seek to avoid the other twenty-three hours of the day. Decidedly undisciplined, we insist that it’s too hard, that we caaaaan’t meditate, can’t focus. Yet we keep showing up, keep paying people to remind us to be present.

YOU ARE HERE, Beth said firmly as we shifted from one asana to the next. Reach up to the ceiling with both hands and lengthen into a gentle backbend. You are embodied. What does that feel like? Bring your hands together over your heart and close your eyes. Fold forward, uttanasana, standing forward bend. Can you fan your feet to feel the edges of each toe on the mat, the outside of your heels in contact with the earth? Step or spring your feet back, adho mukha svanasana, downward-facing dog. Can you feel the places that are tender where you might need to back off? Is it possible to accept those sensations as a moment in time? This is what it’s like to be here now, alive in your body. Do you have to fight it? Judge it? Come forward into plank pose and hover for just a minute.

Plank is a love-hate pose, especially for those with shoulder problems, because it calls for upper body strength. You’re hovering above the ground, realizing just how strong Jean-Claude Van Damme actually must have been to pull off those movie stunts. All the while, you’re negotiating how much longer you can hold the pose (Ten seconds? Five seconds?) Your mind springs into action, the pose becoming a contest to outlast your neighbor instead of an effort to inhabit the form with your body in all of its vulnerabilities.

Is the twanginess in your shoulders more about weakness from disuse, which can improve, or is it the calcified remains of injury? You plunge into the past, replaying circumstances of the hurt, the months of therapy, remembering how easy this pose used to be, how potent you felt. When will –or will it– heal? Maybe you’ve been babying it when the shoulder actually needs to be strengthened. You consider changing your weightlifting routine and off you go: disengaged, disembodied, a rat’s nest of thoughts instead of an integrated, present human being in plank pose.

Beth reminds us, “YOU ARE HERE.”

It’s unusual to turn forty and not have to contend with several minor injuries. You trade these grumbles like baseball cards with middle-aged friends: I’ll swap your corns and bone spurs for shoulder impingement, a torn ACL and a detached retina. Some of you no longer ski or snowboard; others have stopped running. You’re not even old yet and you’re shuffling around like there’s a disabled parking spot out there with your name on it. When a whipper-snapper complains about being almost thirty…in two years…you wish you had a cane to club him with.

It’s hard not to compare and contrast the state of your embodiment today with what it once was; the vigor of your twenties and thirties happened only moments ago. Still, you can no longer press 200 pounds with your legs, at least not without creaky knees or tendons. The college students sharing your lane at the community pool lap you with whip-sharp kick turns like it’s nothing. You mistakenly assume that the high level of function you knew is normal, meaning a baseline for the present and the future, rather than a short-lived pinnacle that comes early in life. You begin to reason that, if you take care of yourself and you’re lucky, the downward slide will be gradual, but underneath you suspect that you don’t get a say.

The fragile decline of embodiment can seem depressing when laid out like this, but it’s funny, too. I tittered as I took hold of the pink box of Phillips pro-biotic pills emblazoned with PROMOTES COLON FUNCTION on the front. It screamed YOU ARE HERE… IN LINE AT BARTELL DRUGS WITH SOMETHING THAT SAYS COLON ON IT FOR EVERYONE TO SEE.

My doctor had sent me in search of meds after the second severe flare-up of fever and abdominal pain, concerned that I might have picked up a parasite or bacteria in Colombia, or that the effects of January’s food poisoning were lingering. While we waited for answers, I had to allay this severe intestinal distress. Grimacing, I waited in line until it was my turn, keeping the box tucked in my hand. “Hello, ma’am, how are you?” the check-out girl asked cheerfully as I placed it on the counter.

I narrowed my eyes and nearly demanded, “Do you see what I’m buying here?!” but instead opted to stew about her calling me ma’am. Doesn’t matter what you purchase –cough drops, lice combs, yeast infection meds– they ask you the same question in that same chipper voice. No wonder why old people are grouchy. We drag ourselves to the store to buy expensive crap to keep our faltering human bodies going, and they’re asking us how our day is, like they don’t see the ailments that we’re plunking down in pharmaceutical form before them. No one buying an enema kit is having an especially good day, even if the kit is for someone else –the implied assistance is worse than the procedure itself, gauging from the couple next to me in line– and by the way, calling us ma’am adds insult to injury.

Then, it sinks in: I’m the same age that my mother was when I thought she was too old to relate to. She was a ma’am, an adult. She had a mom car and a mom purse. She no longer wore cute shoes with heels over an inch high. As I paid for my colon pills in my flat Timberland boots (“Would you like a bag for that, ma’am?”) I realized two things: one, I had forgotten to buy denture cleaner for my night guard, and two, I owned a mom car (still under 40,000 miles after nine years) and a mom purse (damn you, Garnet Hill.) Worth noting that, while I may have backslid into wearing leggings, there is not a power in the universe that can force me to don mom jeans.

So, which was worse, the fact that denture cleaner AND colon medication made it on my shopping list, or that I had forgotten the denture stuff, which might indicate an early onset of senility? Was it the fact that I was buying this stuff at all? And when had I become ma’am to everyone? This week alone, three people asked for my career advice which, I realized, is only something people do when you’re old enough to actually have advice to give. One of them was half my age, which sets me squarely in ma’am territory.

This wouldn’t be the only time that I would leave a place chuckling absently, shaking my head. My symptoms demanded that I produce an –ahem– sample to determine the nature of their origin. I emailed my physician about the dilemma of retrieval. “Dear Dr. X, As a command performance at the lab is unlikely, are you thinking that I should collect the sample at home? Should I use a plastic bag? (Sorry, this is so gross.) Any suggestions you can share are welcome.” As I hit send, I laughed nervously, feeling embarrassed yet entertained by the ridiculousness of my questions as much as the predicament itself.

The elderly deal with these effects of embodiment all the time, which is why health as a discussion topic trumps weather any day. I made this comment to everyone who asked how I was doing. Let me tell you about my digestive tract and how I came down with fever, not just once but twice. I think it’s from the food poisoning, but I might have a little intestinal hitchhiker. I can’t tell if I’m hungry or if it’s just stomach cramps, but I’ve got to eat something, you know? The pro-biotic drinks I usually take aren’t as good as these colon pills (I highly recommend the Phillips brand.)

The joke continues to be on me, of course, wondering when my insides are going to feel “normal” again. I read that, sometimes after a severe event, people develop lactose intolerance or IBS. Someone likened it to upsetting all of the furniture in your apartment – you need to give the good bugs time to settle back in, find their right place between the sofa and the coffee table. While they do, this unsettled sensation is the new normal. YOU ARE HERE, I thought, so get used to it. Despite my attempts to focus, I soon became lost in thought, devising how to collect, package and transport my sample, concerned that I might have to take it with me on the bus.

In all my worry over logistics, I psyched myself out for a few days. There was nary a specimen to be had. On the plus side, it gave me time to get comfortable with my plan as it developed. If things started moving on Friday, was there enough time to stop at the lab before work? I imagined being discovered on the aptly-named Route #2, as several riders had dogs who find me out immediately. Instead of the bus, I could take Car2Go during the week. Maybe I should aim for an evening drop-off when my schedule is more relaxed and I could drive over? The weekend would be best –I could get street parking if I went early– but was the lab open on Saturdays?

In plank pose, hover your knees just about the floor and take three breaths. Now gently bring your knees to the floor and lower yourself without letting your belly touch first. Bring yourself down in an integrated manner; go slowly and don’t allow your core to shut off. YOU ARE HERE. Lengthen your legs, bring your arms to your sides and lift up, arms and legs, into shalabhasana, locust pose. Breathe.

Watching my mother develop a terminal illness when I was a child is one cause for my underlying angst at growing older. It isn’t so much about vanity, although don’t get me started about wrinkles and creases. It’s more about scary math, like how many years are left before I’m the same age that she was at her diagnosis, or how many years until I’m the same age she was when she died. Today, those gaps are narrower than ever. It makes me hope with the kind of fleeting hope that you hope you never actually have to hope with that I will escape her future, the seemingly small complaints that metastasize into a massive and uncontrollable ailment.

Instead, I whip out funny stories and let the gross-out factor guide me. Better to employ humorous revulsion for the task at hand as a means of garnering advice and attention at a time when I don’t want to think about that possible future. This is avoidance, I remind myself. I listen for Beth’s voice: YOU ARE HERE.

So began my Saturday. The scientist in me felt confident with my established protocol: turn off the water to the toilet and flush the toilet until the tank and bowl are empty, yielding an unimpeded surface for sample collection. Have a disposable transfer device at the ready, as well as a makeshift containment system. While untested, I believed that my three-part system would hold — it had to, since I didn’t have the opportunity to pick up a sterile kit from the lab ahead of time. These items were laid out at the ready like surgeon’s tools.

A phone call revealed that the lab opened at 8 am, giving me plenty of time to drive to yoga after dropping off the sample. As I handed it to the young woman in the white smock, she looked puzzled and tried not to laugh. “I’m not sure this is going to work…” From a brown paper sac, she removed the labeled Ziploc bag with the disposable Tupperware container inside. “What time did you collect this?”

“Six-thirty this morning.”

She furrowed her brow, but it was apparently an acceptable time frame, so she left to ask the technician if they could use it. I waited in the stiff phlebotomy chair where they’ve drawn my blood before. For once, I wasn’t nervous to sit there.

It was kind of funny, after all, how much I had dreaded navigating this sequence of events, completing this extra chore whose doing I resisted more than the actual knowledge of what might be wrong with me. Like in yoga, the mind flees to fields of distraction rather than remaining present with sensation and discomfort. I had fretted for days, which made it all the more anti-climactic when the woman returned to say that it was going to work out fine. “Good thinking to use a clear container!” she praised.

From downward-facing dog, raise your right leg behind you and bring it forward between your planted hands. Bring your back heel down and raise your arms into warrior two. Feel into the edges of your feet and your back heel. Square your right knee above your toes and roll your right buttock underneath you. Enliven your left leg — don’t let it become an inert kick stand. YOU ARE HERE. Soften your gaze and feel your strength streaming out through your arms. Lean back and open your chest to the sky, as if the person behind you is providing support. Give thanks that you are healthy enough to practice today.

As I walked out of the lab, the young woman called after me, “Have a nice weekend, ma’am.” I turned to thank her, ready to begin my day but not ready for the title that everyone agreed to confer upon me —ma’am— or the lot of humanity embodied within it. A developing self-image takes time to actualize, if not practice.
