I get asked this question quite a bit. The research is in and if you are already a fit adult at any age, I may add, you may be ready for it. I recommend you working with a certified personal trainer who can safely access when you are ready for this type of training. A researcher by the name of Tabata found that 8 rounds of 20 seconds of bike riding followed by only 10 seconds of rest increases fitness levels, decreases body fat and will even help you lose weight. This study was done with a cardio type of training and not heavy weight lifting like they do in Crossfit.
YOU are your biggest competitor. When you feel tired and want to quit, push because you KNOW you can do it. Today I went to a local Crossfit facility (box) and did the WOD as is or RX'd instead of modifying. Half way through, I really thought I would have to change my kettlebell weight not because I was tired but because I kept getting passed by in the workout. After taking a deep ass breathe, I exhaled and let my need to stay in front of the pack go.
