Chances are that after a certain age you won't have the mental or physical energy to even desire to do all that much.

I know quite a few people who retired quite well off and instead of traveling the world spending all this money as they thought they mostly just watch a lot of TV and sit on their phone. They don't even spend their social security check a month and they are perfectly content with this life.

Many people have confused the reality of old age with marketing from retirement firms and mutual funds.
