WWE Hall of Famer Mick Foley recently did an interview for StarTribune.com, and the following are interview highlights:

How many concussions do you think you've had?

Unfortunately, I had too many for me to count really.

Have you been approached about donating your brain for study as many NFL players have?

I have been approached. These are some tough questions here. You see how quickly I did those autographs? We got through a few hundred people fairly quickly. Signing my name on that form to donate my brain took a long time. It's a big step, but if other people can learn from what I've done, I'm willing to do it. I believe as long as I can continue to say the words Boston Center for Traumatic Encephalopathy that my brain is still working OK.

You must have an enormous tolerance for pain, given this lore about you fighting with a separated shoulder.

You've got to make sure we talk about that in past tense. I did have a tremendous tolerance for pain. Now, not so much. Almost anything [brings me to my knees now]. I’m a guy who used to be fairly fearless. Now, please don’t tell me I have to walk down a flight of steps. [Wrestling] was tough on the body, the knee joints, the back, and so stairs are difficult.
