Zika is spread by mosquitos. They are tough to control. It will bite four or five people at one blood meal. They can breed in the amount of water it takes to fill up a bottle cap or, theoretically, even a drop of water. You have to get rid of maybe 90% of them or more before you protect people.

Health is correlated with quality of life. If you get regular physical activity, have social connections, control your cholesterol, keep your blood pressure at a normal level, don't smoke - these things can make an enormous difference not only in how long you live, but how much you enjoy your life in those years.

Physical activity - even if you don't lose an ounce, you'll live longer, feel healthier and be less likely to get cancer, heart disease, stroke and arthritis. It's the closest thing we have to a wonder drug.
