Anyone else gear cold really easily and have a low heart rate?

I get cold at the littlist breeze and often time start shivering before people start to feel cold. Sometimes I will shiver so bad it will be hard to control my arms. Like eating Skittles will be hard because I'm shaking. Also my resting heart rate is like 48-52 and I've noticed that all of my friends tend to have heart rate of 70-90.

Does anyone else have this too?
