Does jumping a bike into water hurt parts on the bike like bearings?

Well, yeah. Bikes are fairly well sealed against rain, but if it goes all under water can make its way into the bearings and get them to rust. Most bikes survive a dunking, but if you want to treat it right you need to pull it apart for a relube.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
