Simple game, very fun.

Simply ask a question to your mother on how something can kill you

EXAMPLE:
Person 1's post: "MOM, how can not having a pen kill me?"
The person below states how, then asks a question.
Person 2's post: "Because, if you don't have a a pen you can't take any notes. And if you can't take any notes, you can't study. So you can't get grades. And if you get no grades you don't get a job. And no job makes no money, to buy you food. And if you're starving, you're skinny, and therefore, ugly. And if you're ugly no one can love you, which means no marriage, which means no children, so you get lonely, and being lonely makes you depressed, and depression causes sickness, and sickness causes DEATH.
MOM, how can an PS3 kill me?"

I'll start.
MOM, how can breathing kill me?

Let's take pure oxygen as an example of how breathing can kill us, son/love.

Because..our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called hemoglobin. If you breathe air with a much higher than normal oxygen concentration, the oxygen in the lungs overwhelms the blood's ability to carry it away. The result is that free oxygen binds to the surface proteins of the lungs, interferes with the operation of the central nervous system and also attacks the back part of your eye, the retina, which you'll learn about in biology! Hyperventilating air at ordinary pressures never causes oxygen toxicity (the dizziness is caused by carbon dioxide levels dropping too low), but breathing oxygen at pressures of two and a half times more than the normal amount for more than 16 hours can lead to irreversible lung damage and, eventually, you can die!! 

Mom, how can being on the computer too much kill me?

Mom. How can firecrackers at home kill me?

mohammedroxx3 :

Because Firecrackers when let off, explode, which can cause a fire. Fires can spread to clothing, paper etc. The fire can gradually grow and grow, it can even burn the telephone line. Without the telephone line we cannot call emergency support - fire brigade. Without the fire department, our house will continue to burn up in flames. If the roof of the house collapses, and I'm in my place, the kitchen with you, we can be trapped or even crushed. Leaving us lying under the dinner table, dead.
