You read that right. Now let me try to prove it.
Look at these heat maps for the hairiness and baldness. I think it’s safe to say that there is a correlation with the two.
Wonder if it has anything to do with the Mediterranean diet? Probably so. But balding is a much broader problem than that. It’s really only a matter of time. Two thirds of men are bald by 60. And we know the aging mechanism. So we can call balding and hairiness part of the that.
We know that stress can cause balding. And we know that aging can cause stress. Therefore, aging can cause balding. But we already knew that.
So why don’t women go bald? I think it may be because they don’t change as much. I’m guessing the average woman’s head changes much less than the average man’s [in volume]. Unrelated fun fact: women are also more likely to have strokes.
Asians don’t go bald as much. And they are more likely to have severe strokes.
Chemo causes people to go bald. You know this. We even have cooling caps designed to help people on chemo lose less hair. Why in the world would this work?
So if baldness is about time spent out of equilibrium, does it serve a purpose? You would go bald at the same time you get hairy, theoretically. Your brain shrinks and your brain entropy rises. The hotter your head gets, the more brain entropy you have, and the more likely you are to die of a stroke or a heart attack.
Baldness is a mechanism to prevent strokes. If you think about it, even thinning hair would help lower the head temperature, just not to the same extreme. So balding is your body quite literally adapting to a more stressful environment.
Edit: Looking back, this may be too big a logical leap. So what causes strokes? It happens when your brain pressure gets too high. Think about the correlation between glaucoma and strokes.
So how could people just suddenly go bald? Some sort of stress. It could be caused by emotional distress, physical stress, mental strain, or any number of things. The real problem comes when you don’t have the mechanism in your life to combat whatever stress there is. So instead of restarting every day, you begin dying little by little.
What if my head didn’t shrink? It doesn’t matter. If you have more energy in the same black box, it’s the same as it getting smaller. [Boyle’s Law]
