I didn't think I had anything particularly interesting to offer, but then it occurred to me that I have a relatively rare medical disorder: my body doesn't produce any testosterone naturally, so I have to have it administered by injection. As a result I went through puberty over the age range of ~16-19 years old. If you're curious feel free to AMA.

(also, bonus topic that just came to mind: every year I write/direct a Christmas play featuring all of my cousins, which is performed for the rest of the family on Christmas Eve. It's been going on for over 20 years and now has its own mythology, complete with anti-Santa. It gets more elaborate every year and now features filmed scenes, with multi-day shoots. This year the villain won, Christmas was cancelled for seven years and Santa became a bartender (I have a weird family). It's...kind of awesome? If you're looking for a fun holiday tradition to start AMA)
