i feel for you Chris. I'm in a similar position although with only one torn bicep and two very dodgy knees (and about 100 little annoying sprains and strains) i haven't given up on competing completely, but at 44 i have to except the fact that this is a young mans/womens sport where competing is concerned. but that doesn't mean that i have nothing left to offer my students.
your an inspiration and proof that there is life after your competition career is over
