Also, if you’re in an area with a lot of vegetation, you’ll move the umbrella to the side so it doesn’t brush against anything. It’s pretty much an instinct. If it does hit a branch, the umbrella rolls in your hand when it brushes against low hanging branches (it doesn’t just get snagged). If it was attached to your head you couldn’t do any of that.
