I rarely get sick and when I do it's not very serious and usuallh lasts less than a week.

Still, I once vomited so much I got dehydrated. Only lasted 1 day, though.
Some years later I got sick during a skiing trip to Andorra because IDK what the pizza at the ski resort had in it but it made me real sick. That was the first time I've ever been more than 1 dsy at a hospital (I was 2 when the pizza thing)

Worst part is that I have no food allergies so it must've been that it was contaminated

EDIT: as for injuries, most "serious" would be when some pliers fell on my foot from the shelf. And nothing happened. Yes, it was pretty painful, but nothing broke. No bones, not even the skin...I guess I'm sturdier than average :)
