Regular exercise helps make us more alert and energetic, by releasing endorphins which is a chemical that improves our mood.
This is very true, and it is almost like the fight-or-flight response, where your body gets the adrenaline rushing and that is when you hear about people being able to lift cars and jump from 6-story buildings. It is a natural instinct of survival that we all have inside of us. Hope this helps.
If there were a fire, explosion, or bomb threats in schools, for example, are required to evacuate but if it's a sniper or shooter then they do a lockdown. Because if the shooter is on the outside and they decide to evacuate then they could get shoot so most schools and places do lockdowns.
So the answer would be a sniper. I hope this helps!
