Physical Danger
Depends how much you tend to get your hands dirty. Depending on your situation, you may be involved in much of the blueprint design aspects of a project but not as much on the actual construction—other designers prefer to be as hands-on as they can get.
This second type is more at risk of getting themselves in some physical danger. Any time you're dealing with saws, hammers, nail guns, and other such terrifying tools, there's a chance you could be rushed to Urgent Care at any second. If you're good and you know your way around a miter saw, you'll probably be fine, but lose focus for only an instant and bad things can happen. You may only be able to count to nine for the rest of your days.
