Highly inspired from the course
CSC2206: Systems Modelling and Analysis,
I came up with the above probabilistic Markov Model for my life.
The very high probability transition from the awake state to itself is
partly due to the Graduate life and partly due to the coffee machine
in our DB-Lab (BA5260). The very high probability transition from the
sleeping state to itself is intrinsic to me; I really like to take long naps.
