Tall men are the most romantically successful group on earth, bar none: more successful than rich people, accomplished people and educated people.

Most people couple within their own height range- short couples are 8 percent apart, midsize couples are 8 percent apart. The exception is talls. Tall women, meanwhile, date men who are approximately the same size, 0 to 5 percent taller; extremely tall women go for men 0 to 2 percent taller. Tall men are kids in a candy store, dating whomever they want.

The tallest adults are the ones who had the most childhood and adolescent growth before puberty started; puberty typically tacks on a standard nine inches, and then the game's over. "The children who are going to be the biggest adults are those who are tall by age one or two, and have a relatively late puberty," says Rosenfeld.

Kids from small families grow about an inch taller than those from large families. This is true regardless of income and social class, because a body can't grow well while fighting off nine siblings' cold viruses.

Exercise stimulates growth plates, by putting pressure on bone cells, forcing them to specialize and create new cells. Too much pressure, however, damages the growth plates, which are soft and fragile...The rule of thumb is that lifting one's own body weight (in push-ups,pull-ups, etc) is fine at any age, and kids over fifteen can lift weights.

We smugly assume that we are the tallest humans to ever grace the earth. Quite the contrary. The Cro-Magnon people living thirty thousand years ago were about our size and 10 percent more muscular. Hunting, gathering, when food sources were abundant, was an exquisitely healthy lifestyle.
