In regards to the no swimming rule, you might get a cramp but only if you push yourself too hard and even then you probably won't drown. It's similar to if you're running and go too fast too quickly and get a side stitch.

My dad made me do his favorite hamstring stretch (the only hamstring stretch he knows) every day with him. It wasn't even a very effective stretch.

Also wasn't allowed to wear make up. Ever. Even now I barely use any (just some eyeliner here and there).
