> wearing a helmet somehow reduces the odds of exercise Helmet paranoia DOES reduce the odds of exercise. On a group level, at the level of public health, that's PRECISELY what it does. I encourage you to read about it, that's why they call it the helmet paradox. This piece is a nice summary. http://www.howiechong.com/journal/2014/2/bike-helmets http://www.howiechong.com/journal/2014/2/bike-helmets Bike helmets protect our heads, but they also do the following: 1. increase your chances of getting in an accident 2. discourage cycling Here's what to do: 1. If you want to be healthy, ride a bike instead of driving. 2. If you want to be even healthier, consider maybe putting on a helmet, but be mindful it doesn't increase your risk-taking behavior. I choose option 2, but option 1 is also great.
