I haven't eaten coconut for 7 years, and the other day I was by a coconut, and I started sneezing.
You cant on purpose. Sometimes it can develop. But I know a few people who have it and believe me you dont want to have an allergy.
No, you cannot make yourself allergic to something. You either are highly allergic, mildly allergic, sensitive, or non-allergic to any substance. Chronic exposure by sensitive people to allergens by actually help to build immunity to the allergen itself.
Maybe your nose is allergic to the earrings.
No, It is a virus that cannot travel throughout other people just their own self.
Something can become swollen from an allergic reaction.
Well it depends if you are allergic to your pet or if you are allergic to something your pet rolled in. But I do not think that if you are not allergic to them or anything else in the area you live in than no you can not get sick because of your pet. (you might be allergic to something your pet rolled in if you are sick)
to make yourself belive in something you have to belive in yourself.
Yes, you do. If you are allergic, perhaps there is something that can substitute it?
Unlike yawns, just seeing someone sneezing won't make you need to. Sneezes aren't contagious like that. If you sneeze right after someone else, it's likely do to a lot of dust or other particles in the air irritating both your noses, or you could both be allergic to something in the area.
Yes they can if the material it is made of is something that the one using the pillow is allergic to, or the fillings of the pillow cause allergic reaction ( fluffs ,feathers ).
Not unless you are allergic to it or you get food poising or something, it usually doesn't.
Yes
Please don't cut yourself.
