6'4"... 193cm.
I used to be able to dunk a basketball, but no longer. When I was ~24-28 or so, that was my peak in leaping ability. Then I slowly got older, fatter, and I can't dunk. Back when I was hitting 29, 30, etc., I used to take a note in Google Calendar... "I dunked a basketball today" to record the last day I could do it, because I could tell I Was losing that ability. That day was Sunday, August 17, 2014.
So many 6 foot + folk here, and yet folks still think it's cool to recline their seats on planes.
Think of those of us burdened with long legs.
As a person who is 6'4", I testify that I think people who complain about seat recliners are being hyperbolic and stupid, woe-is-me entitled complainers. I barely fit into economy airline seats, but someone reclining in front of me has almost no tangible effect on my sitting comfort. I have long legs and high knees, too. I believe that if you're tall like me and people reclining is a real negative in your life, where yo uthink it should be banned or people shouldn't do it, then you should pay for extra legroom seats or reserve rows in the front of the plane.
