See how wide the new hire age spread is now, vs. 25+ years ago?

It looks like it's age 27 to 62 today, vs. only about a 10-15yr. spread back then (24-40ish).

Then go to the left side, start at the age 55 line and follow it across to about the 4,000 mark below.

All those dots above the 55 line are retirements in the next 10 years.
