I think KSH has it spot on, except I'll add one thing to what she says and that is PLEASE carry an Organ Donor Card.

Sometimes in life we have to diversify often to keep our loved ones happy. Instead of doing competitive racing, perhaps instead you would consider riding for charity? Maybe organise a ride to raise money for the neurological unit that worked so hard on you or to raise money to help brain-damaged people or some similar worthwhile cause?

Racing might be in your blood just now, but given a chance something like what I've suggested could also get in your blood and be very rewarding for you.

I wish you luck in whatever you decide to do.
