Young people can go all-in and take big risks because they still have the cost of trial and error and the courage to start over. In this bull market, those who achieved super high returns were mostly young people. But as you get older, it's better to diversify your investments. The psychological stress can directly translate into physical harm. Mood affects health, and aside from a few people with exceptional mental resilience, most people aren't suited for going all-in with high risk. If this year you once had a maximum profit of 200% but ended up with only 50%, chances are you'll still feel bitter about it. So, managing drawdowns is the top priority for balancing investment and health.
