People are living longer, so the career you expected to cap off at 40 years could last 60.

There are very few people who can work 40 years and save enough money to not work for another 30.

Get ready for a 60-year career with a special series on your money briefing from the Wall Street Journal, Wednesdays in September.

From the Wall Street Journal, this is Bad Betts. I'm Ben Fulti.

This will end very badly, ugly for you, and I feel for you.

I'm sorry, you may be a bad guy.

You know what, say here's the thing, you're right.
