Not at all. It depends mainly on your bone structure. I'm around your age and only weigh 103 pounds, but I have a naturally tiny frame.
It all depends on your sex and height. If you're seriously concerned, see your doctor.
That's not bad, that is just how your genes are made up. If you want to gain weight I would suggest lifting weights of course and including cardio to keep the most important muscle strong, your heart. There are two types of protein powder to take. Theres whey which would be more for before and after a work out because it is absorded in 30 minutes (from what I've read any ways) and ceasin which is a meal replacement. Ceasin is taken before bed by the majority of people. I would suggest going to bodybuilding.com for A LOT MORE information. NOT AN ANSWER! Thanks for your comments, but I already exercise and do cardio and it seems not to work for me. I'm currently 110lbs and I can bench 155lbs 3 times and can Squat 205 more than 10 times. By the way I was the guy who posted the question. Do you think I should take creatine??
I will tell you this, a 19 year old should weight aboutat least 160 and over. To tell you the truth who cares youare beautiful and just the way you are. Don't listen some people on weight. just remember that not everyone is an expert and also you are young and you don't need to worry about your weight. I know this is probably bad coming from an 11 year old but, I know a lot for my age.
The average 5ft tall 19yr old should probably weigh between 90 and 110lbs (14lbs to a stone), any less is not good but muscle mass and body shape do also come into it so a bit more isn't bad.
It's not good nor bad it just means the weight to length ratio is significantly smaller than most softball bats currently used.
Weight gain and health problems
no
yes that is bad means you are over weight and that you should think about losing some of it
Halitosis is not related to someone's weight. The leading cause of bad breath is bad oral hygiene.
It is currently set to be released in 2012.
Bad for what? Weight? Yes, that would be bad for a human, but small for an elephant.
It depends on the height
