That's it. Just Grow Up! Stop blaming other people. Society. Doctors. Your Genes. Parents. Spouse.
Just Grow Up and start being ProActive in your own life.
There is no Magical Pill you can swallow to make yourself healthy or fit. You are the only one who can take action to work towards health.
If you put synthetics, pharmaceuticals & dead stuff into your body, you can't expect to get much Life out of it. It's your choice. But if you choose poorly, stop belly-aching about it (and all the aching body parts).
