Of course! I hope I never stop. I like to take my older dog for a run. He loves the exercise, and it’s fun for me, too, especially when I can listen to music while I ride.
I live in a hilly place though, so it’s tricky. I can get away from my house just fine, it’s downhill to a long and well-maintained bike path that takes me basically everywhere I want to go. But to get home, I have to walk the last ten minutes to get up the hill, pushing my bike. I just can’t do it otherwise. Gravity is too strong.
