It sure saves your mom a lot of time when she comes bicyclin for that booty late at night to my house. The parking is bad around my place is what I am saying.
Actually though, riding a bicycle is like a super power even if you are only going 5 mph on flat ground, I would be shocked if it wasn't like a superfood for your brain so long as you weren't taking big risks while doing it.
Funny you should mention big risks: I read a study a few months ago that said downhill MTB is still a net gain for your overall health even with the extreme dangers the sport can pose. People really underestimate how dangerous being sedentary is.
Yep. Iirc, cycling is not only the safest way to cross any distance, but it's statistically safer than sitting on a sofa. (Lots of accidents happen at home.)
