The President of the United States asked his doctor to lie about his height and give him an extra 1 or 2 inches. It matters to him.
Depends, of course. Also, sometimes height sucks. I'm about 6'3"/6'4".. 6'4" with shoes on, 6'3" and some change flat footed. It helps me in basketball. I'm bad, but I've always been a good rebounder, good defender, good in the post because my length helps. But, it blows flying, going to the theatre, sitting in a car, sitting at a desk, sitting on the train, buying houses, buying bed frames, traveling to foreign countries, and just about anything else that involves interacting with a world that is designed for someone 5-8" shorter than you.
Bought my wife and I a treadmill 6mos ago for our basement. I kinda thought I might not be able to use it, but... nah. Can't. I can sort of "Walk" on it, but any speed faster than the slowest, flat setting, and my head hits the ceiling (Drop ceilings because of pipes, wires, etc). Even if I was able to pull the drops up ~2", my head would still go through the ceiling when running, or be so close that it wouldn't work.
We were looking at houses 2 weeks ago and likewise... there was this really nice, but kinda architecturally weird, and pretty inexpensive house in a town near by, like $100,000 less than what you'd expect similar square footage/age/quality/rooms to be in that location... And as soon as I walked in, I was like "Uhh, nope, this is why it's $100,000 less." The ceilings on half of the first floor were just over 7". Any sort of beams or door frames were barely over 6'6", maybe even right around my height. That house was constructed fucking weird, and I don't know why they'd do that, but some builder screwed it up in some way... ANd that was the result. Even if your head clears a room if you're 6'4" and the ceilings are 7", you feel like you're in a funhouse and it's claustrophobic.
For dating it helps. I haven't dated in... 8 years, I'm married, but ... back when I was single, I know if I was like a 5'8" average build guy (as opposed to 6'3"ish average build / dad bod guy), I might get a couple second looks or something, but honestly, being moderately tall, a ton more women look at you, comment on your height as an ice breaker, etc. I even think it ends up building into your personality because it's just reinforced behavior. Obviously this isn't the case for every tall person, there's plenty of tall, insecure men of course, and plenty of shorter, very confident men, but ... I dunno, I think if you get second looks enough times, consistently, for your whole adult life, then you end up building more confidence when dating. What's kinda weird is I've never really been into tall women. My wife is shorter, 5'5" or so, and my tallest ex was probably... 5'8" or 5'9", but I dated one girl who was 6'1" and... I dunno, it was intimidating for me. It wasn't a deal breaker or anything like that, it didn't work out for other reasons, but I can definitely say it was something that just took me off guard at first and I felt unsettled by it. It wasn't until the "relationship" ended that I kinda realized why she was physically intimidating to me, evebn though I've grown up around tall women (my mom was almost 6" when I was a kid, one sister is 6'1/6'2" ... which is probably why, my older sister used to kick the shit out of me when we'd fight as kids, and it's probably stuck with me). It's just a weird thing that is definitely something I subconciously noticed.
