wrestlervic saidI bet his insides look all black and sooty.
No bet about it -- they do. His lungs are blackened without doubt, and he's at great risk for multiple forms of cancer, and for emphysema. A friend of my partner was a smoker, tied to an oxygen tank now, lungs shot and mostly confined indoors, won't live for much longer. A miserable end to his life.
And BTW, on the general topic of looking good on the outside: when I taught college PE for several years, my male students often already had great bodies as they began my course, 6-packs to die for. I never had a great build, and at the time I was mid-30s, at the end of my prime.
At the start of each semester I would administer a strength test to all the new students, and a body fat analysis. And guess what? Those 20-year-old hunks were hollow! Not half my strength, and body fat percentages running into the 20s! I could run circles around them, with more stamina too, and a body fat that varied between 9 and 11% in those years.
What looked like bulging muscles on those guys was in fact riddled with fat, with just a portion of the strength inside that their appearance promised, just nicely shaped. One can be fat without having a beer belly; any nutritionist or sports medicine specialist will tell you that.
Moral: don't judge a gift by its wrapping. It's what's inside that counts, and in more ways than one.
