Before you shout
ME!, consider this: In a recent book about space travel ("Packing For Mars"), the author said that you can expect about 15 to 20% loss of bone-mass during 6 months of weightlessness. And an expedition to mars (round trip) would take about 3 years. You have to wonder if you'd have any bones left by the time you got back.
Whatever bones you have left might break upon your return-landing, as you would have to withstand a force 10 to 12 times earth's gravity.
What about cost?: It has been estimated that it would cost $500,000 billion.
Any volunteers?
