I'm 5'8, and I feel like I'm just at the cusp of being genuinely disadvantaged for it.
Its just short enough to be made fun of for not being able to be intimidating, and just short enough that most women get the ick to 75% of women.
A 4 inch difference (or 3 inch to err on the safe side and lie to women about the last 1 last inch to 6') is easily achievable with surgery, and it would make a massive difference how I'm treated by society. statistically my dating pool would 4x. and this is at least somewhat indicative of how much better I'd be perceived by society at large.
Also, frustratingly, I have everything else. I studied/worked hard and got a great job/salary. My face is at least 8/10, and to adapt/succeed in online dating I became a great conversationalist (probably the reason why I've been able to have relationships anyway).
I'm also convinced the reason why I'm only 5'8 almost certainly has to do with being malnourished for most of my childhood. When I left highschool at 18 I was only 48kg/105lb. I was so weak that using the military to escape wasn't an option, I went the 'Student living on canned beans' route instead. Also my cousins, who's parents are the same height as mine, are all 6' ish.
I grew up in a poor/trash family, yet I've managed to overcome them entirely, aside from this.
So I feel like its my most significant flaw, but something I can't change.. Except I can, with limb lengthening surgery. I know its painful but I just don't care that much.
I've just turned 27 and the $25k it would cost (some place like Turkey, whos hospitals are apparently as good as US/EU..) I can easily part with. I'm also taking a 3 month sabbatical from work so now seems like the best time for it.
Given my reasons above, why shouldn't I go through with it?
