Well, I don't know how to do either one of those things, but I would say I would rather not know how to ride a bike because I feel like knowing how to swim is a more, I guess, a common skill that's more important, especially when it comes to like, I guess, life changing or anything that could put your life in danger. Like if you need to save someone from drowning or stop yourself from drowning, you definitely needs to know how to swim.
