Not being able to do sport as I did is certainly one. Remember the very day it hit home, I was involved coaching youth football and I decided we'd have a pre season sprint the length of the park. Half way I thought "ok press the accelerator and get past this lot"....nothing happened. Legs didn't do fuck all and when the big centre half went past me my brain just went numb. Couldn't understand what just happened until I realised I just found out what the pros mean when they say the legs have gone. Can barely swing a golf club properly either now. Even my darts averages are plummeting by the year.
Have you got to that day yet when you look in the mirror and say "Who the fuck are you.?"
Though erections I can still do.....well last time I tried anyhow.
