I am the 6'7" monster who is married to Dirona, and also could legitimately click the final option on the poll. As she said, she can wear heels of any height and I still tower over her. I guess high enough theoretically exist, but (to my knowledge) she doesn't own any like that.
Honestly, being this tall is a pain in the ass most of the time. 6'3" or 6'4 was good. Most things still fit. Probably 6'3" is the better of the two. Now... I buy cars first on what fits. A little under 10 years ago, I went into a Toyota dealership and I couldn't fit in ANY of their vehicles. Not just cars, ANYTHING they had. No test drive, period. Varies per manufacturer, but so far Chrysler is the best for having SOMETHING I can drive (usually there's actually a choice with them). Most others, 1 or 0 vehicles I can fit in, let alone drive comfortably. Clothes aren't too bad, but I was really mad when Land's End stopped carrying tall sized jeans.
I'm not that far off the scale (37-inch inseam, my torso is massively tall), but still, 36 just doesn't work. Very sad.
The real disappointment came last week at the Calgary Stampede: maybe 50% of the rides I wasn't too tall for (anything where the upper restraint rotates down can't go far enough without impacting my shoulders).
Sucks.
Oh well, I do have it better than the very short, but it's not "great" up here either. Has its advantages sure, but by no means universally good. 6'3" was better.
