And while I could look at pretty much any of my male blood relatives -- grandfather, father, brother, nephew (sorry, guys) -- and reasonably determine that my genes have just finally caught up with me, I think I'd prefer to blame the chemo.
First of all, hair loss is a well-known side effect of chemo, so it's not unreasonable to throw the blame that way ("I'm not balding, I have cancer"). But more important, if it's the chemo I can reasonably expect my hair to come back when I'm through with the cycles -- Come back, hair! Come back! -- whereas if it's the genes I'm pretty well hosed.
So I'm going with the chemo (hope springs eternal).
But this experience has raised a weird question: where does the hair go when it falls out of your head? It's not showing up on my pillow. It's not accumulating in the shower drain. I don't make piles of hair when I sweep.* It's not anywhere, including, increasingly, not on my head.
It's like the Tooth Fairy got her wires crossed and is taking my hair instead -- though without leaving loose change behind.
Oh well. At least I'm saving money on shampoo.
* In theory; to confirm that this is, in fact, true I'd actually have to sweep.
