Your mates invite you over for the night. Both your mates are drinking and offer you a drink.
If you decide to drink there are many potential risks. These include potential depression, heart and liver disease, stroke, diffferent types of cancer as well as general sickness.
If you decide to drink, a negative outcome would be you could feel sick and you'd have a greater chance of getting cancer or other health issues later on in life. A minor positive outcome would be tha you would feel that you fit in with your mates.
If you decided not to drink, a positive outcome would be you would stay in good health and not put yourself in any harm and a negative outcome would be potentially your friends thinking you don't want to be like them.
The best decision would be not to to drink because it would be much better for your health if you didn't drink or had water or soft drink.
You can still have fun without making silly decisions and doing the wrong things.
