It's a matter of priorities. Younger folks with disposable income are more likely to spend it on travel, cars, home purchases, etc. By the time you get 50+ you hopefully have paid off the home, done the majority of travel you wanted, and have gotten over the need for a fancy new car every year. You've got a much better idea of what really makes you happy - and you have the means to indulge it without so many competing expenses...as you sense your mortality more, you are ready to indulge before time runs out. That's also why you see so many old guys driving fast 2 seat sports cars. If not now, when?
