Scientists say staying sexually active is one of the best activities we can do because it releases several positive hormones in the body, increases intimacy and also has other social and mental benefits.
Recent studies show that frequent orgasms, at least 100 per year, can increase Life Expectancy by 3 to 5 years. One study of men with a high frequency of orgasms concluded they may be able to reduce their mortality by as much as 50 percent. Sounds hard to believe, but even 10% is a lot.
