Definitely don't believe usable human DNA on a stamp can survive over 120 years unless very carefully preserved since the beginning
Sorry, I hit the enter key by mistake. Wanted to add: when collecting oral fluids for HIV tests, we use a buccal swab which needs to be in contact with the oral mucosa for a few seconds in order to absorb a sample good enough to perform an accurate ELISA. So I too doubt the viability/usability of a saliva sample on an old stamp. Still, I will continue to use a sponge to seal my envelopes...that glue tastes nasty ;) -S
