The older you get the less time remaining for investments to compound (or rectify, if there's a downturn). The probability that it's worth delaying gratification declines because the future value is lower, and the odds of you seeing that future is also much lower . The odds of you dying this year doubles from 30-50, and doubles again from 50-60. That information means you should gradually save less and start doing more of your top bucket list items by (before) 50.
