Questions: Health & Fitness

I was just going over someone else's question about height and re-reading the comments that were there. Well, apparently, 183 cm (6 ft for all those who still use the old units of measurement) is really tall, but where I live that's kind of average. I see people - both women and men - who are as tall, or taller than that. There must be something about the northern hemisphere that stunts people's growth. Then again, it could simply be because Australia, being the best, healthiest (thanks to Medicare, which is 100% FREE) and most advanced nation on Earth, this is only to be expected.
