40,000 Americans are injured by these every year…what are they?

A: Toilets.

If you’re wondering how we get hurt by toilets, here goes: Pinching due to splits in plastic seats or by splinters from wooden seats, or if the toilet itself collapses under the weight of the user. Older high tank cast iron cisterns have been known to detach from the wall when the chain is pulled to flush, causing injuries to the user.
