How many times have you been to a hospital and thought, I could have fixed that myself if only I'd known how? With no equipment. In my case, never.
A lot of the time they just send you home. Knowing that ahead of time would be phenomenally useful.
At least one time. Considering it's the only time I've been to the hospital for myself in the last 25 years, though, that's a lot! :)
That article was way longer than I thought it would be.
