I havee no clue xxxxx?

I'm quite tall - about 5ft10 and I always think I look a bit on the chubby side - but my friends all say I'm thin - I think probably the worst judge of how you look is yourself - because you're probably going to be looking at every angle for hours on end and you convice yourself you have fat ankles or long arms or something like that! Your friends are the best judge! But if you do feel worried about your weight - check your bmi - you can put in your height and your weight and it tells you whether you're the right weight for your height - search on google bmi calculator - 20-23 is a normal weight (you'll know what I mean when you do it!)
