[this answer](https://rpg.stackexchange.com/a/64320/14848) currently suggests swimming while wearing a full suit of metal armor would be a reasonable thing to do *in real life*.  In actuality, jumping into water with a full suit of metal armor on may well end in your death.  While most people are, I hope, educated enough to realize that the physics proposed in that answer is just completely wrong and/or reasonable enough to realize that extra weight you can't easily remove + deep water = very bad idea, I'm not confident that everyone is, and so the fact this proposes deadly real-life activity as if it were not deadly concerns me.  Is this something we should do something about?
