Human

Human are full of weakness, we cant be too cold or too hot, we cant live in water for too long, we cant fall from too high, we cant fly, we cant live without air, we cant be too hungry, we cant survive without water for more than 3 days, we... cant stop aging, we cant survive mentally without friends for a prolong period of time, we cant cure cancel...

We only have earth as a livable planet so far, we have only a thin layer of atmosphere between the outer space and oceans, we CAN chose not to pollute the air with not smoking, we CAN chose not to drink bottled water to reduce the wastage, we CAN chose trans-fat-free biscuit to stay healthier, we CAN care for others to stop little argue which may lead to WAR.

We are human. Not animal. We CAN chose smart act. Be smart, stop smoking.
