Not to be a downer but if you look at his cheeks in that photo above you can see they are flushed and pink. That is a sign of poor circulation. Not blushing as some of you may assume. My brother had a 98% blockage of one of his arteries and displayed the same signs! We were fortunate in when his heart attack hit we were only 2 blocks from the hospital.
These symptoms don't just appear in one day, they are usually present day to day but most people don't know how to recognize them.
I didn't agree with Tim on some things but i liked to listen to his perspective. May he now do commentary for the angels above.
