Body Mass Index or BMI will take your height and weight and tell you if your overweight or underweight, you can plug in your info yourself at

http://www.nhlbisupport.com/bmi/

but I did it for you and your completely within normal weight.

your bmi (body mass index) is 19.9

BMI Categories:

* Underweight = <18.5

* Normal weight = 18.5-24.9

* Overweight = 25-29.9

* Obesity = BMI of 30 or greater

So your at the low spectrum of normal weight, so I wouldn't worry if I were you.
