I'm pushing 64. Four stents - they are bionic, so I don't thi k about them when I ride. They are part of the reason I can ride, and I don't hold anyback because of those little tubes.

As for the hearing aid issue, being able to hear approaching traffic isn't going to save your hinie. You aren't going to ride off the side of the road because you hear a motor vehicle approaching, and you'll never know if or when a car is about to hit you, anyway.

It's legal to drive a car when we are deaf, and it's no different on a bike. I say, unless it's illegal in your jurisdiction - and maybe even if it isn't - crank up your headphones with some classic rock and just ride. ;-)
