Oh Grasshopper. When we were young we too thought we were invincible and could do what we want and eat want we want. Then when you get older you discover your lifestyle was responsible for the cancer. When you are 20 years old, ( or 16 ), you believe you have at least 50+ years ahead of you. Then when you learn you have cancer, ( rather it be skin, liver, lung, brain, or other ), you wish that maybe you had done things slightly different, but now it is to late and you take each day one at a time. I still remember when they claimed that flame broiled hamburgers caused cancer, that was my favorite and I just said to myself, if I eat this, just how long will it take to cause cancer, then proceeded to chow down a few. It's a tough decision to make but as you get older you realize you need to pay attention more to your health.
Now it's my turn to get off the soapbox.
