We do things for a reason... BULLSHIT

We do things for a reason is a piece of quick talk, it sounds good until we apply a bit of reasoning and analysis, and is essentially bullshit. The definition of bullshit, in this case, is the speaker/writer does not care if the statement is true or false, it is just for effect. We can do things for a reason/logic or the following incomplete list:

• Reason/logic (included for completeness of this list)
• To achieve a goal or objective (instrumental)
• Stimulus driven behavior, it just feels right or good
• For pleasure, what ever it is
• for fun, or a challenge
• a belief, or as proof of belief
• emotion or for emotional relief
• comfort, pleasure... it just feels good to do it
• stimulus or fixation on doing that thing, habit
• ego, because I could
• social/cultural belief  

So why we eat may be for no reason at all. Note that stimulus made the list.
