I'm younger than you I guess ;-) but suffer a low male life span in my family.
by rights I have about 28 years left!! and I'm half way though my life. Anything else is a bonus.
"Live for today and Plan for tomorrow."
I live by this motto and think it is healthy.
I could be in a high powered job earning lots of money but I choose a friendly less stressful environment to work and for just enough money.
By taking the stress out of life this should give me extra time but if it doesn't then at least I've had a happy life.
