According to a study published in the Archives of Internal Medicine, any exercise or physical fitness help in keeping the kidneys well. If we keep ourselves healthy and quit smoking and exercise regular it will protect us against heart disease and early death. It also prolongs survival after colon cancer.

A study was done by Dr. Jennifer J. Otten, of Stanford University, California hints that sometimes all it takes are small behavior changes. They found, among 36 overweight and obese adults, that those who reduced their weekly TV time by half burned more calories than those who made no changes to their TV time. So another big thing is say NO to TV.

In 1986 a study was undertaken, which included around 668 men who were treated for colon cancer. With this, some questionnaires were sent to these people containing queries regarding their health and physical fitness. In January 2006, 258 of the patients died, out of which 88 died from colon cancer.

"Men who were physically active after diagnosis of nonmetastatic colorectal cancer experienced a significantly decreased risk of colorectal cancer-specific death, as well as death from any cause," wrote Dr. Jeffrey A. Meyerhardt, of the Dana-Farber Cancer Institute in Boston.
