Protein should provide about 15% of a healthy person's daily calories. As a rule of thumb, people of both sexes and any size will do fine with about 60 grams of protein a day. Athletes who have large muscles and work out hard may need 20% more. But even that's not very much; 8 ounces of chicken or 6 ounces of canned tuna, for example, will fit the bill.

What's a man to do? Fortunately, he does not have to choose between his bones and his prostate. The solution is moderation. The Baltimore Longitudinal Study of Aging, for example, found no link between a moderate consumption of calcium (about 800 mg a day, two-thirds of the RDA) and prostate cancer. In addition, a randomized clinical trial of calcium supplements of 1,200 mg a day found no effect on the prostate, but only 327 men were in the calcium group, and the supplementation lasted just four years. Finally, the Harvard scientists speculate that a high consumption of vitamin D may offset the possible risks of calcium, so a daily multivitamin may also help.
Many WASH interventions targeted mothers and their caregiving behaviors for children. However, these interventions were applied to entire households and not individual household members. Larger community-based hygiene and sanitation initiatives broadly reached more people in the community (131). However, certain populations such as the elderly and young children might have limited access to public infrastructure, such as public latrines, particularly if there are physical and economic barriers to accessing them (136).

If motivation is your hang-up, change your exercise routine every 14 days. A University of Florida study discovered that people who modified their workouts twice a month were more likely than to stick to their plans compared to those who changed their regimens whenever they wanted to. Boredom didn’t appear to be a factor; it seems people simply enjoyed the variety more.
