there are a lot of things I miss about working in scicomm but I gotta say I do Not miss the daily ordeal of trying to explain to people that just because you havenât reacted to poison ivy yet does not mean youâre immune forever
TIL some people are immune to poison ivy (so far)
itâs more like everyone has a secret number of times they can be exposed to it without consequence, above which, god help you! sometimes that number is like. âtwiceâ. for some people itâs much higher.
though Iâve also heard of people reacting to it for years and years and then losing sensitivity later in life for no apparent reason. anyway thatâs impossible to explain to classes of school children.
this is such a great time to add here that this applies to everything else on earth as well, and its just that poison ivy is particularly likely to get you sooner rather than later. but yeah you also can and will just suddenly become allergic to even normal stuff sometimes, after years of not reacting! if everyone knew this a lot of Mysterious New Illnesses would be solved a lot quicker
I know many stories of entomologists who develop chitin allergies and have to leave the field⌠my uncle became deathly allergic to chocolate after a few years of working at a chocolate shop.
I bonded with a college professor one time because we had both gotten poison oak/ivy enough times that neither of us can touch mangoes without gloves now.
this is suuuper common for people who work with animals, esp. in scientific research. people often have to leave the field because their allergies get too severe to continue working around the lab animals
