Very good. You're superior to sharks and every other animal.
Humans are superior though.
How do you know they live "well" without it? You know they live without it but the "well" part is just your opinion, unless you're dr dolittle.
Your opinion, my opinion is humans need aids to live, have to modify their environment to be comfortable, to work for a living and keep the tax man in the manner he has become accustomed.
To me that doesn't make humans superior but it does make them weak.
Animals live, they eat, they play, they ****, they don't kowtow to the boss or bow down and pay the tax man. Thats pretty good living ti think
