I think it's preference, do you want to enjoy your life while you're young, or bank that you'll live to an older age, and enjoy life when you're old.
Similarly, having more money hits serious diminishing returns. Watching a 500$ TV vs a 5,000$ TV doesn’t actually change much in the moment. Jump all the way to a 500,000$ home IMAX and watching a terrible movie still sucks.

I still enjoy life in the present but I do sacrifice a bit of it so I can also enjoy life when older.
If you don't want to completely sacrifice today for tomorrow you simply adjust the age related weight in the Excel sheet :-)
