Survival of the Firmest: The Hard Science of Healthy Lifestyle and Erectile Function

Survival of the FIRMEST is a guide to good health and better sex. A firm body leads to overall health with FIRMness in one particular area (an erection) showing that the cardiovascular system is healthy. Nitric oxide (NO), a natural body substance, is crucial for both erections and blood vessel and heart health. Obesity, diabetes, excess dietary sugar and fat, too much alcohol and lack of exercise cause the lining of blood vessels to produce less NO. Increasing anti-oxidants, folic acid, omega-3 fats, calcium, vitamins C and E, and L-citrulline in the diet or with supplements helps to increase NO production. This authoritative guide is a must for improving couples' sex lives and preserving what they already enjoy. Simply following the authors' recommendations will lead to a more satisfying and lasting sex life and at the same time enhance overall health and long-term SURVIVAL. The final chapter will help couples preserve everything they've worked so hard to achieve!
