Tim's puffy cheeks

As I watch the AMA's, I can't help noticing that Tim McGraws cheeks look really puffy. He's grown out his beard to cover, but it's not quite working. They actually look swelled up, you know that shiny look a person's flesh gets when it is filled with fluid. And his eyes seem a little tired, too.

What do you think?

• Is he sick and taking some form of steroids to help him get well?
• Did he have some kind of plastic surgery?
• Is he just frazzled, tired and worn out?
• Or, do I just need to get my eyes checked?
