I’m a man with no brain But, I’m outstanding in my field. Who am I?

I am one of the few things in life you can pick freely

I can warm your hands and hold your morning drink, steal your wallet in the street, or stare back at you in the mirror when you look at me. What word am I?

a breeze blows by and a scent rolls in, the aroma wafts and the gagging begins. what is this magic thing, that can come from eating beans, or many other fibrous things? remove my first, and some people do proclaim it to be so.

RAWR! I am a dinosaur that ate a dictionary.
