I am 34 and it pegged me at 32. There were some good suggestions (ahem, more flossing, more fish etc), but I think I would have fared better if I hadn't seen the following (duh, yes I knew this) paraphrased in the opening of my little report:

"You have had a number of major life stresses this past year."

So hopefully next year I will be like 23! ;^)
