It means you're normal.

1.73m and 62kg = 20.7(1569381).

umm. 1.8m i think and i weigh 67kg. so that makes me...

about 20.6. but i think im lower than that!

1.77^2=3.1329
65kg=well 65kg. so 65/3.1329= huh. 20.7 thats wierd. i used to be 17!

that's good then, you're no longer underweight, if that's correct.

Mines too big to mention

If it was, that wpuld be impressive. Say, a googol? (though that would require you to be the size of an ant weighin more than the planet :P).

Hmm lets geustamate. umm id say conn was about 85kg and hes the same height as me,

so thats 1.77^2=3.1329

so 85/3.1329=27.2. thats not too bad. ive seen worse on the net. like 30 or more. anything abpove 50 and you should be dead. really.

Yeah, not the worst I've seen. Oh, and 50 doesn't mean your dead, just that you probably can't move... (*shudder*)

no you shuld be dead. ok 2m tall and wieghs hmmm, 600kg. thats really high no tie to work it out! be back l8r

that comes to 150, which is very high. However, BMI does not state at which point you would die, it's just a measure of health, and high means you will be lucky to survive, but wont neccessarily die.
