This is the answer right here. Hook up with a local sailing club and take classes. If you love it, make friends with other sailors and rent the club's boats.
If there's interesting stuff to see near shore, and the tides are manageable, then kayaking is also great. It's cheap and easy to get into, and great exercise.
Despite my best efforts to get away from computers, I still find myself attached to them in one way or another during most of my waking hours. Lemmy is my computer time that acts as a mental break from other computer time. Connecting in an even more intimate way sounds horrible.
World War 2 vastly overshadows all other conflicts. Something like 3.7% of the global population died. Some individual countries lost more than 10% of their populations. No other conflict, or group of regional conflicts, comes anywhere close.
