They're simply huge.

I don't want to scare anyone, but I just checked myself in a mirror and I think the bags under my eyes are going away. I will usually give myself a quick glance every now and then to make sure I resemble something approaching presentable: no blood caked under my nostrils, no seeping wounds on my face or above the collar. But it's rare when I actually look at the man in the mirror and ask myself "How are you? Do you look healthy?" And darn it all if I don't actually look like I'm getting enough sleep for once.
