Nothing strange. Heath is 6'1" and Jake is 6'. Taking into account Jake's hair and the absence of it on Heath in these pix, I am sure we can account for the illusion. 
Also, Heath is shown bending his knees a little in some of the pix (see below).
Okay -- it's the Heath bending his legs that made Jake look taller in the picture I was talking about it. I wasn't looking at the tops of their heads for height, but at their shoulders. You can always see Heath is taller there, at the shoulders. Actually, though, I thought Heath was 6'2" and Jake was 6'. But there's only an inch difference, huh? Mystery solved. Thanks.
My dad was 6' and I always liked that height. But also I like shorter. My mom's side, all the men are short-ish. Besides, if I wanted to be with a man, I prefer someone not so tall. I don't like feeling like "the little woman." (I'm 5'5".) I know some women like that, but I don't. That's why it's nice being with women, more the same size...if that matters to one at all. Actually, nothing matters when you fall in love, or when you find a soulmate. We could be a zebra and a giraffe...
