Answer:
OK. People have asked me this before and I don't know what's so hard about it. If you get a drink and suck on the straw your using your tongue to pull the liquid into your mouth hopefully. If your using your lungs that's a waste of good breathing time. Grab a drink and use a straw to suck it in, that's what you do with a cigar - suck it through don't try to use your lungs.
