That was really freaky. Apparently, I have until Jan 8th 2028 when I will be 71 - probably due to being so overweight. The freaky bit about it is that my mother died on January 8th - back in 1976. Spooky or what? Still, mathematically speaking, the odds are only 1 in 365 so it's not so odd really I guess.
I did a bit of playing around with the figures. Apparently, getting myself down to my medically proper weight would only add 3 years BUT, cultivating an optimistic outlook rather than a "normal" one would add 25 years. Although the numbers are subject to many variables, I can well believe that a positive outlook sustains life longer because there is evidence that happy people generally have better immune systems than unhappy people.
