Can anybody explain why my nose goes into overdrive when I’m in a cold environment and produces lots of extra fluid causing my nose to run. If this is a protection mechanism then what is the fluid supposed to protect me against? Many thanks 🙂

If your nose runs and your feet smell, it means you are built upside down.

True fact.
