I remember the first time I came to Florida.

I was a kid. It was February, and we wanted to go in the pool. My grandmother thought we were crazy.

"It's 72 degrees outside! You'll get sick!" she said.

But dad told her: To us, this was like summer. We were from New York.

We moved to Florida permanently in 1995. I have lived in Florida ever since. Last month, I stuck my hand in the swimming pool to adjust the pool vacuum and shivered.

It was in the 80s, but the water felt like ice. And Tuesday night, I finally relented and put the heater on.

This all occurred to me while reading the comments on this cold weather meme we posted to our Facebook on Tuesday:

Many people thought this was funny. Some people seemed a little annoyed. One Florida native especially called out TV stations for making fun of Floridians in a comment that appears to have since been deleted.

I get their pain. I grudgingly admit that, as a New York ex-pat, my blood has "thinned."

That's what we say when we have become acclimated to a warmer climate. Florida natives and those of us who now wear hoodies while walking on the beach tell the newcomers: "Just wait. Give it a couple years. You'll be cold, too."

The thing is, your blood doesn't REALLY thin. It's just something we say. Scientists say feeling cold may actually have more to do with perception than actually being cold.

What happens to people who adapt to warmer climates is the capillaries in the skin dilate, and it takes longer for them to constrict for cold weather. So if you're used to 80-degree weather all of the time — like last month — and then the temperature drops 20 degrees, you feel cold. It's tolerance.

It explains why some people who come to Florida from up north now are "winter lightweights" while others think we're all crazy.

So how about you?

Take part in our viewer polls. We want to know, Florida residents, how cold is too cold for you? And, transplants, how long did it take for your blood to "thin out?"

We want you to tell us your stories online, too. Head to our Facebook and Twitter accounts.

We'll share your responses on Friday.
