I thought of some more benefits:

• You will get to plumb the depth of your psyche (to see how far down it goes  )
• The same (hopefully) is true of how high  :oh.. but you may want to get off before you reach the top.
• Your may be able to confirm if you have an addictive personality, in which case you should stay clear of other addictive things eg: alcohol, cannabis, computer games, etc

As always though, good luck and don't gamble everything all at once
