There was a time not that long ago when country legend Tim McGraw thought it was time to retire. For a guy who prided himself in keeping in top shape, getting hit with injuries that required two knee replacements and four back surgeries was not only painful but soul-crushing. As he told a concert crowd recently, “I’ve had four back surgeries and double knee replacements, just in the last couple of years. Things were getting really bad, (and I was) getting depressed over it…And this spring, before I had my final back surgery, things were getting really bad, so I was seriously contemplating and figuring out how to walk away. I didn’t want to, but I didn’t think it was going to get better.” Thankfully, he’s doing much better; losing two icons to retirement (with Alan Jackson hanging it up) in a short period of time would have been tough on country music fans.
