I got to thinking last night that theoretically, with enough hair, the air resistance would slow you down so that your terminal velocity would be low enough to land unharmed. How long would it need to be? How would one go about calculating this?
I assume you need some kind of drag coefficient and a density for hair to start with. Not sure where to find that information.
For what it’s worth, if you don’t train for this you can get some nasty scalp separation injuries.
