I am 6ft even, and not qualified on this topic.
However, if it means anything to anyone, I would gladly give up a few inches of my height if it were possible to share, and I mean that sincerely. Take a small mirror, look at your face head on. Now lower the mirror 5 inches and angle it up and look at your face again. You'll see how much older you look.
Now position that mirror 5 inches above your eye level, and see what I see.
See how young you look. Believe me this is...
