Check your bottle before reusing

A dentist's wife has a tumor in her uterus and needed to remove it. Her doctor told them the possible cause of his wife's tumor is by some chemical which only affects women. The chemical is mainly found in plastic water bottle. It is not the water that affects you but the chemical released from the bottle. You must check on the bottom of the bottle. There is a triangular sign and there is a number on it. Make sure the number is higher than or equal to 5. Then this bottle is save to use. Whatever number under 5 will release the chemical. For most bottle water, the number is 1. Remember to check and stop reusing those bottles.
