I think government costs for a retiree are about NZD27000 a year.

A government should be subsidising a good deadly recreation for say NZD10000 a year. Assume expected life remaining is 10 years, assume recreation has a 10% chance of clean death, assume low chance of expensive ongoing chronic outcomes.

Suggestions: Car racing, climbing, fentanyl habit, boat racing, ocean sports, Russian roulette, foreign legion soldiering, free climbing, wingsuiting.

Maybe a better way would be to allow people to gamble with their lives to win a few tens of thousands (need to balance costs against expected savings). Pay out to winners, but saves the government their expected lifetime of expenses for the losers. Let the old and unhappy roll-the-dice and the winners get to live it up a little . . .
