+test result changing towards healthier lifestyle

....so I'm 38 years old, an already mother of a 20 yr old daughter and a 17 yr old son who have BOTH left the nest!  I have developed a little more experience in child thru young adulthood rearing and added a few more strings of patience....i wonder how many of us finally decided to change our lifestyles with such a change in our circumstance after finding out we were pregnabt?
