Here's a possible way of working age into the equation:

Start at 100, and subtract the decedent's age from it to get your points. If the selected person dies at 85, the player receives 15 points. If the player selects a 40 year old, he or she would receive 60 points.

For selections over the age of 100, we should deduct points in the same manner if they last the year. If they die, they should yield only one point.

Have a daily double, in which the player receives double points for two picks, who die within 4 days of each other. Perhaps, we should have designated days, i.e, holidays or the birthdays of the participating board members, where points would be tripled.

I have other ideas, but it's starting to get a little morbid.
