My dad was staking out some pea plants, when he bent down to pull a weed and got the stake right in his eye. He had months of repeat visits to the eye specialist. We were very worried but thankfully no long term damage. He also did the classic error of unjamming a clogged lawn mower whilst it was still plugged in. Resulting in severed tendons in his fingers. He was home alone and drove himself to hospital with his hand in a tea towel. He is in his 70s now with a claw hand.
