TRT?
Is that like trick or treat with a Mexican pro in Tijuana or something?
I'm 55 y.o. broken back fused in two places, L4/L5 and L5/S1, basically have three vertebrae as one. my neck is screwed, from the base to C1. both my knees mcl's are no bueno.
I surf weekly, smoke pot daily, bone my wife as often as she'll let me, get morning, noon, afternoon, evening, midnight, wee hours of the night wood, never lift a weight other than my swinging my garden tiols in my garden, hobble around in pain, and only take any pills for the pure fun of it, recreationally... as in get wasted every way once in a while, or knock out for any flight over 5 hours in duration.
All this crap is in your head.
If you aren't amped to surf, maybe the surf around you is crap, or too crowded to be any fun anymore.
If you aren't amped about your significant other, maybe they aren't sexually exciting to you anymore.
If you are a fat fook because you sat your ass at a desk job for too long? Ask yourself if the paycheck and pension plan were worth that?
