The greatest irony of the meme shown below...

...is that the person who created it clearly has not YET started paying attention...in logic class, or in science class.

Maybe I should create a web series of these adventures:

"If I'm not supposed to eat the entire contents of a saltshaker at once, why does my wife keep putting salt in my food?"

"If water is so good for you, how come people keep drowning in the ocean?"

"If arsenic is a deadly poison, why aren't all the people who eat rice dead?"

"Why am I not supposed to eat the whole jar of Metamucil if Metamucil keeps me regular?"

"If carbon dioxide can cause convulsions and loss of consciousness, why do we allow so many trees on our planet?"

"If One A Day vitamins are so good for you, why are you limited to only one a day?"

Once Guy-Who-Just-Started-Paying-Attention figures out the answers to these questions, he should probably start looking into the dangers of dihydrogen monoxide...
