I started HRT when I was 46 (last year). How I wish I had started when I first had a mind to, when I was 22. But in those days, information, support, and resources were hard to find--I didn't know it was possible--or I told myself it was impossible--or something ignorant like that--I talked myself out of it and suppressed the desire until it burst out into the open under its own inner power. Wow, it looks like they have really raised the bar for youthfulness these days, if you think 23 is old, kiddo! You're one of the lucky ones.
