The difference between life and death is just a heartbeat away. You can lead and live the cleanest and most health conscientious life imaginable and live to an old age or die very young. The most important word in that last sentence is "Live". Enjoy your life with all the ills and always keep in mind that most of us don't harp on or regret the things we did but we do tend to regret the things we didn't do. A "Lifetime Guaranty" is only limited by your life time that has no guaranty. Just go have fun and try not to accelerate your demise doing stupid crap.
