people who feel older die sooner

Here's an interesting study that caught my attention, now that I'm 70.  A study was done beginning eight years ago, with people who were 65 years old at that time.  They were tested to see if they felt older, younger or the same as their actual age.  then they were followed over the next 8 years.  According to the results disclosed this morning, 25% of those who felt older died during the 8 years, 19% of those who felt their actual age died in the same time span while only 14% of those who felt younger died.  Their conclusion seemed to be that if you feel younger you live longer.  Some days ago I told a friend that on the inside I felt 40 something.  I'm really liking that answer now.
