I started riding at 19, now 29. Wow, 10 years have got behind me.
I've enjoyed riding for leisure and commenting on the bike; married with my first kid and there's no mention of me selling. I think it helps A LOT that the father of one of my really good friends has been a responsible rider his whole life, and looking at him and his family (his wife also rides) puts a lot of holes in what people say about motorcycles and motorcyclists out of fear and ignorance.
I have a 65 year old coworker who loves his r1, and I would very much like to be that guy. It would be so cool if my d675 was still kicking when we're that old.
I've seen people get their m1 all gung-ho and stop there. One buddy bought and petered out. A friend of a friend stuffed his r6 into a tree on our local country back road. (He's changed but alive and able bodied.) One guy I went to high school with died in a freeway collision. Another buddy lost two of his friends to moto accidents. A new found friend lost his wife when they crashed splitting lanes not long ago. So yeah, people have come and gone for one reason or another.
The only thing that keeps me from riding is my job. I used to commute on the bike when I was an apprentice, but I noticed that some people didn't take me as seriously, and it was a major inconvenience if my tools needed to move from job to job. And the bike doesn't loan itself to my new duties. So it's a weekend thing now, you know, when I'm not working ot, or traveling, or getting every moment I can with my wife and daughter.
