Hi, there! (:
Well for starters - you shouldn't take your friend's medication because it can internally harm you. Chances are if it's prescribed by a doctor for someone other than you it's not made for your body which can lead to a very dangerous reaction on your end.
Another reason is that it's not actually legal.
But lastly, it can lead to a road of addiction, or even you going and trying to experiment further, and it could lead to long term damage.
I hope all is well, and you pass! Good luck, rockstar! (: If you have any follow up questions, or even a comment on what i've wrote - let me know! (:
1. aerobic means "with oxygen" and anaerobic means "without oxygen"
2. aerobic can mean small exercises meaning you aren't using too much of your body's muscles and bones to workout. Anaerobic can mean big exercises meaning weight lifting.
3. With aerobic exercise the oxygen is carried through your breath to the muscles giving them the energy they needed. This is basically an example of a warm-up before an exercise. Anaerobic however makes you out of breath quickly because without doing the warm-up and you just go into the workout you are making yourself weak and not have enough energy.
Hope this helped :)
