6'3 here. This is the answer. 

Sharing an anecdote for those interested:

A few years ago, I switched seats with someone before takeoff because their mother asked me since they were nervous and wanted the aisle. It was a relatively short flight (Philly to Milwaukee) so I obliged and got the window seat instead. 

This mother was supposed to be in front of her son, but we switched and she was in front of me instead. She leans back, so naturally my knees are in her back and she got mad at me because she wouldn't be able to sleep.

I laughed in her face (since she essentially ASKED me to sit there) and put my headphones on. She continued to recline because pettiness I guess. I would adjust my legs every few minutes out of necessity, which would move the seat enough to keep her awake. We were both miserable and hated one another by the end of the flight.

Now it's either both our faults or neither depending how you look at it, but the point is that Airlines cram you too close together. If you are in front of a tall person, you will get knees in your back and that's the way it is.

The US needs high speed rail, like very badly.

Man, any rail service would be amazing. I only fly when I wanna go back to Texas and see family and it’s expensive, uncomfortable and somewhat scary (I don’t like the idea of being rocketed through the air…)

Trains? Trains are awesome. Heck, I’d even take buses if the route didn’t require me somehow going thirty miles for a transfer.
