I'm warmer to the touch, which I guess affects others more than me. And... you can feel your heartbeat, your pulse, most of the time... without really trying, even. I'm aware that it's not there, though like I said... I'm accustomed to it. And I haven't been really hungry in ages, either. At first you want to eat out of habit, mistake that for hunger, but it isn't really the same... Hard to explain if you haven't experienced it, though.
