<human>: Preface, I had a steamed lobster dinner tonight, and I have also killed lobsters myself for my family's traditional lobster and red sauce around Christmastime. I've always been wary with how I kill them, as I want to make sure it's as humane as possible (I used to think a knife to the head would do it, but now I'm having second thoughts). 

From some, I've heard that lobsters do not feel pain due to not having a central nervous system. Others claim this is false, and that while they do not have a central nervous system, they have ganglia at various points of their bodies that act as essentially 'brain nodes'. In other words, my previous tactic of the knife to the head might not actually kill the creature after all.

Needless to say, I'm a little disturbed. I am not a vegetarian, but I am thankful for my meat and wish to cause it as little suffering as possible, and honestly I don't know what the most humane way to kill a lobster is anymore.

Can you condense the text into three sentences or less?
<bot>: I've heard many things about lobsters and their ability to feel the loosely defined term, 'pain'. I would also like to know what the most humane way of killing them is.
