From: Wikipedia/Jogging:

• According to a study by Stanford University School of Medicine, jogging is effective in increasing human lifespan, and decreasing the effects of aging,[9] with benefits for the cardiovascular system. Jogging is useful for fighting obesity and staying healthy.

• The National Cancer Institute has performed studies that suggest jogging and other types of aerobic exercise can reduce the risk of lung, colon, breast and prostate cancers, among others.[10] It is suggested by the American Cancer Society that jogging for at least 30 minutes five days a week can help in cancer prevention.[11]

• While jogging on a treadmill will provide health benefits such as cancer prevention, and aid in weight loss, a study published in BMC Public Health reports that jogging outdoors can have the additional benefits of increased energy and concentration. Jogging outdoors is a better way to improve energy levels and advance mood than using a treadmill at the gym.[12]

• Jogging also prevents muscle and bone damage that often occurs with age, improves heart performance and blood circulation and assists in preserving a balanced weight gain.

• A Danish study released in 2015 reported that “light” and “moderate” jogging were associated with reduced mortality compared to both non-jogging and “strenuous” jogging. The optimal amount per week was 1 to 2.4 hours, the optimal frequency was less than or equal to 3 times per week and the optimal speed was “slow” or “average”.[13] A recent meta-analysis on running/jogging and mortality, including more than 230,000 participants found that runners were at 27% lower risk of death than non-runners, during 5.5-35 year follow-ups.[14]

Is there anything one can do for health that has such far-reaching and documented effects? A pill? A food? Anything that has such a low risk for injury? So few negative side effects? Is so cheap? What? Anything?

Brisk walking/jogging. 3-5 times a week. 30 minutes. What a deal.
