- when you finish a run and your whole body is full of sweat and you can't catch your breath
- when you finish your gym workout and your muscles aches and you feel like jelly
- when you go out of your comfort zone and cannot believe what you just accomplished
- when you are in a game and the tables are turned in your favour.
- when you are super hungry and you get to eat
- when you get a new gadget to play with
- when you see your loved one smiling
- when you are close to your loved one
