Hey there. No worries about the age, recently read about a bloke at 51 getting into trials! No age too old for having fun!
Everyone here is happy to help out with any questions you have!
I personally started trials about 8 months ago. Did ride a normal bike to school when I was little but once I got my drivers license I got rid of it. Now, because of trials, I'm wanting to get myself a decent bike again..
Welcome to the forum, you'll enjoy it!
