I'm 41 and my mom still voices concern when I tell her I rode my bike somewhere. I'd say her concern is misguided, but I was hit by a truck about 5 years ago. I wasn't injured, but she did get the call to come to the emergency room. I imagine seeing your first born son strapped to a back board with a C collar on tends to worry a mother a bit.
I still ride, but just to keep her worry low, I avoid the area where I was hit.
