If your health is decent and you don't absolutely need the money, it makes sense to wait as long as possible.
Roughly speaking, SS expects people to die around age 81 or 82. If you think you've got a good chance to beat that bogey, delaying SS should garner some serious consideration. I've known a number of people who started drawing early and later had major regrets.
Edit - My dad was one of those people.
It's awesome when those checks start coming in at age 62 (or some other age less than the normal age 65/66), and your friends and former co-workers are envious. Now it's 9 years later, your heart is in good condition and there are no signs of dementia. Those same friends and peers are drawing 40-50% more than you. You'll have some regrets until you die.
If you die before you ever start taking social security, you won't have any regrets (or thoughts at all) and it won't really matter. Plus, I think your spouse (if you're married more than 10 years) gets that increase benefit.
If SS is just play money for you or your health is iffy, go ahead and draw whenever.
