Why do I go and get snot down my throat?

I don't know what's it is called but after when I eat fast food, keep under surveillance porn, or get cold I get snot down my throat. Explain?
Answers:    It's called 'post-nasal drip' and it's pretty much in recent times what your described - when snot gets into your throat. Here's a quick breakdown of what happens:
ou generate nasal mucus. This can come from a mixture of sources - getting cold and warmed up again, allergies... whatever.

2. you sniffle. Pretty common recoil

4. Nasal mucus is slightly slippery, so it 'oozes' down due to gravity.

5. The nasal mucus irritates the back of the throat where the trachea (windpipe) join to the esophagus (tube that leads to your stomach).
