Im in the let it go club.Ya, shit happens, one has to take the good with the bad. some time all the armor one wears and all the setup on the bike one does will not ever guarantee a non-bruising day.
But the more you doit the better you get, one thing is sure, off road crashes in general hurt but won't kill you, unlike road crashes.
Ride within your comfort zone not of what others say, take it slow and easy at first, your gut will tell when your ready for more. Expect to eventually go down and when you do let the bike go, don't fight it or you may be hurt a lot more.
I have gone down lots off road on the S10 and other then bruises and minor scrapes have always walked away with no more then a hurting pride.
My big question and most important one to ask your self is.
How important is the S10 or any bike cosmetics to you, a lot of guys, including my self try to protect the bike when going down and that is when you can get really hurt.
Food for thought, parts are repairable, replaceable, the body may not be as easy.
Your age and being fit is another big one, we all think we are 20yrs old other then most of us will not bounce back like a 20yr old.
