1.3% in bonds I own, and 1.4% in a fund that own bonds (where I keep my cash while waiting for opportunities to make buys in equities), 8.4% in my DROP account and the rest - 88.8% - in individual equities.
If you go by life expectancy, and per your question that is the way to answer this, then I have exactly 25 years left. For planning purposes I tack on an extra 13 years and have on occasion even looked at the numbers all the way to age 95. As long as my quality of life is good I intend to live forever, but if the quality starts to suck then I'm going skydiving without a parachute.
A pension and health insurance influences where I keep my money and allow me to be more aggressive in the stock market than I otherwise would be.
The bonds are for college expenses and I will buy some more bonds in the next two-three years as the kids get closer to that age. I have those moves planned out, but only a general idea of moving more money into bonds as I get older.
