We tend to discuss unusual topics here. Things like sarcastic fringehead fish, cave burritos, declassified Russian psi experiments, cube-shaped wombat poo, and salamander stickiness.
We indulge in a strange array of podcasts and publications, and my family generally tolerates the way I read aloud intriguing passages from whatever book is currently captivating me. (Right now it’s Rob Dunn’s Never Home Alone.)
Even when my kids were small, none of them got much out of science kits. The only kit-like thing I saved from that time were several large, firm plastic molds meant to be snapped around immature squash in the garden. Presumably, once trapped in these molds, the poor squash would have no option but to grow into grimacing squashed faces. I could never bring myself to do that to any of nature’s perfect fruiting plants, yet for some reason still have those unused molds in a cupboard.
Instead, my family has a long history of doing whatever weird thing interests us. Our garage and front yard have hosted quite a few entirely youth-run projects such as building a hand-cranked forge, welding together a desk out of saw blades, carving runic greetings into stone, and assembling bones back into a skeleton. I guess things here may seem a bit odd. We’ve even scared our mail carrier.
The oldest evidence of the questing minds around here is a list of stats still posted on our frig. It started with a long-ago dinner table discussion about head size and ended when we measured each other’s head circumference. My daughter carefully wrote each person’s winning number. The list was updated as the youngest reached their late teen years, and the list has remained on our frig for nearly 20 years, proud reminder to all that my head is smaller than the heads of the man I married and the four children we spawned.
Because we’re a strange topic household, I wasn’t surprised this morning when my husband insisted his head had morphed. “These bumps weren’t here when I was younger,” he insisted, “and I swear my skull shrunk.”
I assured him that was unlikely. “I’m shorter than I used to be,” he reminded me, “so why can’t my skull shrink?”
I have no medical training at all, but am a whiz at speculation. I noted that spines and skulls are constructed differently, reminded him his height is surely affected by the spinal surgeries he’s had, and generally dismissed the possibility that one’s skull can shrink. He tends to be skeptical of my speculations.
So at 5:30 this morning I found myself measuring my husband’s head and letting him measure mine. Because we have that handy list of what our skulls measured nearly two decades years ago, we were horrified to find both our measurements were somewhat smaller. I tried to question the variables —- were we using the same measuring tape, was our hair substantially thinner, were we checking the exact same location on our heads?
He consulted his phone and quickly reported that, yes, as we get older bones in our faces slide and bones in our skulls shift. (Because life is vastly unfair, age-related changes happen much sooner in women than men.)
I insisted our skulls have to stay the same because they are the right size for our brains. “No,” he said sadly while continuing to Google. “Our brains shrink too, about five percent every decade after age 40.”
We texted each other bad jokes about our shrunken heads the rest of the day.
As my sliding skull bones and I slide through what’s left of my 50’s and beyond, I may take another look at those squash molds. Maybe if I wear one to bed each night, my shifting bony structure will take on the expression of a startled squash in yet another home science project.
Tips for Keeping One’s Brain From Shrinking
Avoid the blood sugar spikes common with processed food to avoid consequences of inflammation.
Avoid smoking, keep your blood pressure down, stay in a healthy weight range.
Keep alcohol consumption moderate and eat a diet rich in vegetables and fruits.
Get regular exercise, even increasing the daily distance walked helps (park farther away, take the stairs, etc).
