One of the first things you learn about driving is too keep your eyes on the road! But we all know about texting and driving already. Some people will get hurt by looking at their phone while walking/traveling. My fiance hit the curb on his bike while playing and messed his hand up.

However he loves the game and has a great time! And he is getting out of the house and I know he is enjoying the outdoors and taking things in because we go together sometimes and both enjoy the wind and the trees and seeing everyone else outside too.

Besides, you're more likely to get into adverse situations or get a minor injury from some activity anyway if you actually leave the house and do outdoor things, pokemon go or no pokemon go.
