The five areas which make up your SHAPE analysis cover most of what affects your longevity. However, there's no particular magic in which area a particular item (such as smoking) might fall. Don't agonise too much over what is the "right" answer. Just choose the answer which is most like you, even if it's not a perfect fit.
Once you finish the questions you will see your results and can decide what to do next. Please note that the Analyser is specifically designed for Baby Boomers and older (ie, for people born before 1961). However, if you are under 45 just choose age 45 and your results will still be quite informative.
