What I'm meaning to ask, with smoking and drinking threads... is why do we as humans do things? I think most of us would acknowledge that smoking, drug abuse and excessive alcohol isn't good or healthy. From a "Spock" point of view, doing those things which have no positive value as far as health goes is illogical. Smoking or drinking beer or doing illegal drugs are not necessarily things which humans must do to survive. However, eating food, breathing air, drinking fluids and water is necessary to sustain life. Who's idea was it to make a cigarrette when the basic idea of it carries no value or necessity? (that was a rhetorical question... I'm sure we all have our own ideas or explanation for that one). We as humans create and sell to our fellow kind things which are harmful and/or deadly. We as humans create the very pop-up advertisements and computer viruses that we as humans seek to avoid. And what of telemarketers? Has anyone really ever bought anything they were trying to sell? Ok, so maybe I'm getting off track. Point is, sometimes I have to look at people as a whole and kind of laugh... as if some logical alien race were to observe us and wonder the value or utilitarian use of a cigarrette; or wonder why we should need "antivirus" protection against viruses when people could have just not created viruses in the first place. Or wonder why one would do drugs when they have bad effects on the body- usually in nature animals stay away from things that aren't necessary for survival (in most cases). I'm not condemning us overall, just saying we are kind of funny creatures. I just as anyone else have my weird habits that don't make sense.
