It's a strange thing but the 'life is too short' thing was a big part of the reason why I wanted to get riding again. Obviously, I don't know personal circumstances and would never question them, it's just odd the way life twists and turns.
I lost a really close brother in a motorcycle accident back in 1983. It was his fault entirely (not looking behind properly doing a U turn on a fast A road). The car that hit him broadside at 60 mph had no chance of avoiding him. I was 18 and he was 19 and we rode together all over the place. Initially, I said to my devastated parents I didn't want to stop riding, which they said was ok but were probably worried sick. Six years later, I gave up biking for their sake. 20 years on, married with two teenage boys, I said I wanted to return to my biking days which I loved so much. My wife was surprisingly positive about it (not sure why???!!!), but I've not looked back since.
I still think about staying safe for my wife's and the boys' sake but, hey, who knows what the future holds and nobody lives forever. All I can say is celebrate and enjoy the things you love now - you can't allow yourself to live life in fear of the future.
