Any Vegetarians/Vegans here?

Tell me why we humans do not salivate when we see raw meat so we can continue the talk.

Tell me why I do not salivate when I see raw vegetables.

Anything raw does not make me salivate, but when you start cooking it you can smell it then you salivate.

Seriously though, salivating is just the anticipation of food. Ever heard of Ivan Pavlovs Dog Experiment(were he rings the bell and gives dogs food)? We condition ourselves to salivate by cooking food. The dogs in the experiment still salivated even when no food was present.
