What radon gas does:
Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked. On January 13, 2005, Dr. Richard H. Carmona, the U.S. Surgeon General, issued a national health advisory on radon.
What Seiko Tuna Divers do:
--They are fucking cool.
--If you are otherwise fit, have a good BMI, don't have BO, and have most of your teeth, a Seiko Tuna will help you get laid from broads who like fit males with good BMI, no BO, and decent teeth, particularly in beachfront bars during Lady's Night.
--They will tell time well below their stated WR depths.
--If your dive computer fails, they will possibly save your life, so you can dive again and take pictures of fish and mussels and shit.
What Seiko Tunas won't do:
--Protect you from fucking radon gas and shit.
