Interesting Fact - Aging

According to research published in Science, you'll age slightly faster standing on a staircase than you do on the floor below.

(It's all because of the time-slowing effects of acceleration and gravity which have been demonstrated in experiments that compare real clocks on Earth's surface with timepieces in high-flying spacecraft and satellites, such as ones used for global positioning systems and these effects are measurable here on Earth. Seemingly the pull of gravity on an object increases closer to the centre of mass, so an object on the Earth's surface actually experiences a slightly stronger pull than one floating in the atmosphere. Now I know why all those rich people live in penthouse suites, they're trying to live forever.)
