The test is not a joke or an absolute on how long your'll need real estate on the planet but more a picture of how well you are treating the carriage that hauls your rearend around. I have an identical twin and up until about ten years ago no one could tell us apart. I quite smoking about 15 years ago and drinking 5 years ago today (it's my anniversary). I was smoking 3 packs a day and could easily put down a case of my favorite brew. Today I am about 20-25 lbs. lighter than my brother and I could run circles around him going backwards. I feel great and actually don't look 60. He still drinks and smokes. We'll see how valid the test was, in the future. Be kind to your bod. It may be a while before you get your next chance.
