How long are you going to live? is a free tool you can use to generate a personalized health profile that tells you the do’s and don’ts for living longer. After a quick 10 minutes of answering ~60 questions about your lifestyle, ranging from dietary habits to drug use to flossing your teeth, Dr. Perls generates an estimated life expectancy, as well as ways to increase it. Although you have to suffer through a few poorly written “always-sometimes-never” questions and several limited response options, it is a quick and easy way to find out how long you have to find the perfect gravestone. Thanks so much to Brian for the tip, the link, and the beginning of this article.
