bulging tummy...

I, personally has tummy not so proportionate with my body, yes I admit I don't do a lot of exercise and in a way makes me less disciplined when it comes to exercising. But not to all aspects of life. I can say I am more disciplined when it comes to studying or as a daughter.

I don't think that you can make that generalization. If someone is overweight, then most likely they are a bit undisciplined in their eating and exercise habits (if they don't have a medical condition causing the weight gain). But that does not mean that they are undisciplined in all aspects of their lives. This is a misconception; there is actually a lot of discrimination in the world directed towards obese people. If you eat too much at McDonald's and live on junk food, but you are not prone to gaining weight, you are just as undisciplined as the fat person- it's just not as visible.

I am a computer programmer so most of the time, I'm sitting. That I think makes my tummy bigger. I think I just need a discipline to exercise regularly.
