Random weirdness

So, to all the manly men out there that like to work outside in their gardens...... apparently a new medical study of 700 men showed that working in the garden 30 minutes a day, 5 days a week can reduce the risk of impotence by almost 40 %. Umm... yeah...... How do they come up with this stuff and more importantly... what man out there is going to listen to this advice?
