At one point I had a health of about 3, not bad. My health currently sits at .8, and I think only one issue caused it to drop so greatly, but I haven't a clue which one it could have been, and I haven't found a way to check.
If there is a way, other than keeping track of it for yourself in a spreadsheet or something, It's NationStates' Best Kept Secret. Sadly, such a thing doesn't exist.
