Viagra may not be the only way for an aging man to stay potent in the bedroom. According to a new study, a weekly dose of olive oil can actually slash a man’s chance of impotence by up to 40 percent in later life, suggesting that it may be stronger than viagra. In the long term, a healthy diet such as the Mediterranean one, which usually involves olive oil, was found to be better for maintaining a man’s sexual prowess than relying on the instant boost of Viagra.
