I agree about high radiation, but I'm not so sure about low gravity.

Everyone extrapolates the problems of free-fall into low gravity situations, but they need not all apply. In fact the human body might thrive under Martian gravity, or Lunar gravity, better than it does on Earth. In a 1 gee environment we have problems with posture, and with falling over, and with blood pressure when standing, wear and tear on our joints, and carrying loads; on Mars or the Moon those problems could be reduced in many ways.

We may experience problems in gravity as low as the Moon's or lower, but I have a suspicion that the sweet spot for gravity is somewhere between Earth's regime and Mars' regime - and it may be closer to Martian gravity than our own.
