Most of what happens inside our bodies we're pretty oblivious to aren't we? I've had a twitch under my eye for two years. What is it? Fuck knows. Is it dangerous? Dunno, I'm not dead yet, so probably not.
Our bodies do loads of weird and wonderful things we needn't concern ourselves with. Like did you know that inside you there is a nerve cell that decides whether your nipples should be erect or not? Because there is.
Scientists from the Karolinska Institutet have discovered that this particular nerve does nothing else but give you hard nipples... or not, depending on the situation. Science.
And it doesn't necesarily have anything to do with sex, and nor is it related to when it gets cold. You can get a nip on at any time.
Co-author of the study, Alessandro Furlan, explains: The study says: "One thing we found was that goose bumps and nipple erection are caused by neurons that are specialised to regulate these functions by controlling the erectile muscles in these tissues." So they just turn on and off like a tap for laughs, it seems.
It's funny isn't it? Some scientists are out there trying to find cures for disease, others are more concerned with creating renewable energies or discovering ways to engineer food to solve world hunger. Now, while all of these things are great it's good to know that there are so scientists dedicated to figuring out the important stuff.
