Age-Related Decline in Strength as Decline Neurons
“What we have here is (a) failure to communicate,” said the Captain in the 1967 film Cool Hand Luke. This line rings true today as it relates to the failure of physiologists to communicate the mechanisms of muscle strength to the geriatrics community, where the lack of muscle strength observed in older adults holds high clinical significance. Similarly, there is a relative under recognition in the scientific community for the potential role of the brain’s failure to communicate with ske...As the neurons controlling muscle fibers die off, those muscles grow weaker. Possibly exercising muscles might keep signals going to those neurons and keep them alive, staving off age-related cognitive decline.

Colonies Will be Built in Space
...the goal of planet colonization has been challenged by a radically different notion of the Final Frontier Created by Princeton professor of physics Gerard K.O'Neill, this new concept is based on one of those revolutionary propositions that are so simple they seem self-evident. The surface of a planet, O'Neill asserts, is not a very good place to house a post industrial society. Free space itself, he says, ist he natural ecological habitat for a high energy, high-growth technological specie...Folksonomies: space exploration

It doesn't make sense to fall down into the gravity-hole of a planet to colonize its surface after you have climbed out of the gravity hole of your homeworld.
