was the decision to quit purely one of "if i dont im going to kill myself"
or
"i cant carry on riding because my bodys too knackered"
if its the former, then just go for it mate. Like you say, you only live once. I've had a really **** year, my parnters grandfather died this year, aged 83, her mother died a month later of heart attack Aged 50. 4 Months later my mother was diagnosed with a fatal brain tumour and given a year to live. Granted her grandad had a good innings, but no so for both our mothers
Honestly, life is just too short to give up on what you live. Because if the motorcross doesnt kill you, something else will
