How old are your Band-Aids?

I was getting my kit together for a backpack and was surprised to see how old and decrepit my first aid supplies were.  Band-Aids falling apart with adhesive no longer sticky; salt tablets and electrolytes which had seen better days, expired Iodine, crushed water purification tablets, a broken emergency spork (critical!); two open rolls of cotton bandages, and all sorts of other embarrassingly inadequate supplies.  Not good.

So how old are your Band-Aids?
