Hello,
I am 19 years old and I just now noticed that I can not tell what sweet, and sour are.


I noticed because my friend gave me a couple of taste tests and I failed them.

I dont have a problem with not tasting sweets. (keeps me staying healthy :))
it has just been bothering me and I want to know why I cant taste it.

I am very healthy, I dont do drugs, I exercise and I have no disorders.

is it normal to not taste sweets and sour?
