We should journey to the Moon and beyond?

Since the Moon has only one-sixth of Earth’s gravity, the heart does not have to pump as hard on the Moon to supply oxygen to the brain. While for a youth this would have an atrophy-type effect, for those advanced in years it can result in a rejuvenating effect, as the heart is suddenly relatively stronger. This allows for longer productive lives for our citizens.This goes hand-in-hand with No. 3. Engineering design will be significantly different in a vacuum environment with no water, wind, rain, hurricanes or tornadoes. Corrosion takes a different form.
