Live Longer

Move to a one story house. It won't help much though.

According to general relativity, someone who lives on the second floor of an apartment building should age ever so slightly faster than the neighbor downstairs — because Earth's gravitational force is ever so slightly weaker. Wristwatches should run faster as well. The experiments conducted by physicists at the National Institute of Standards and Technology in Boulder, Colo., show that it really works that way.

But don't move to the basement just to extend your life: Over the course of 80 years, that slight difference would add up to far less than a millionth of a second. The NIST researchers found that a height difference of about one foot (33 centimeters) resulted in a time variance of roughly a billionth of a second per year.
