Teens vs parents: who's fitter, taller, fatter?

A unique study pits the two generations head to head - or gut to gut

They weigh more, are taller but nowhere near as fit as their parents were at 15, according to a unique study that has assessed two generations using the same tests.

Girls are, on average, 8kg heavier and 3mm taller than their mums at the same age, while boys weigh 11kg more than their dads and are 4mm taller.
