Life happens .... You can't go around living afraid of everything (or anything) or you would never leave your house. Yes I have had close calls, Yes I have had near misses, some my fault, some not. But in 45 years of riding all over the world, I can still honestly say there is no better way to de-stress and relax than a nice ride somewhere (other than Italy, they are insane).
Last weekend, riding on the twisties in the mountains, hearing my better half giggling like a school girl as we went up and down the mountains was the best feeling I have had in a while.
Is it dangerous to ride.... yes, if you're not careful. Most accidents are young (inexperienced) riders without enough training who think they are indestructible.
Do you have to be more alert when riding ... yes, but that also opens your eyes up to everything around you. You really miss a lot boxed in a cage and going down the road. Riding also tends to give you habits that make you a better driver overall.
A friend of mine just had to give up his bike, at age 94 ...... I just hope I can get out of my recliner when I'm 94.
