stairs

Once upon a time Wrath was on his way home. He saw his mom about to open the door to his 3rd storey flat. He decided to run at his top speed, leaping up the stairs 2 steps at a time, right to his doorstep. The next day, his inner thigh hurts like crazy.

Moral of the story:
1. Old man should not exercise without warmup.
2. Old man should do cooling down after exercise.
3. Old man should not do strenous activities.
4. Stairs are designed the way it is for a reason.
5. Keys are meant to be used to unlock the door, not just to put inside your bag.
