Challenges develop fortitude and strength…One of the biggest problems for astronauts living in space is the loss of bone mass due to zero-gravity. With no gravity to resist the astronauts become weaker. In the biological big-bubble experiment known as Biosphere 2, the trees eventually had to be attached by cables to the framework above. This is because there was no wind in the Biosphere , and with nothing to resist the trees became weak and needed support. Similarly, without something to work against – without situations of some gravity – our body and mind begin to atrophy. We need something to press against in life in order to stay strong and grow.
