The Three R's are reduce, reuse and recycle. Print on both sides of the paper to reduce paper wastage in school. At home, on the other hand, avoid buying items that are over packaged with plastic. Use paper or reusable bags! :)<span />
1st: Point at someone and tell them to call 911
2nd: Point at a worker near you and if there isn't one point to a person and tell them to go see if anyone near has a defibrillator
3rd: Start CPR with 30 chest compressions before giving two rescue breaths
A warmup is to prepare gently before a physical performance. A cool down is to do exercise at a lower intensity. They are similar because you can do the same thing for each, such as doing a few stretches, jogging a lap or two, maybe even taking a few deep breaths.
