Your observations are spot on. I was one of those when undertaking my postgraduate studies dealing with fascinating amalgamation of human and artificial intelligence and suffered a lot even for meeting my basic needs like sleep.

I had no idea but with a sudden awakening with the pain, I saw the light at the end of the tunnel learnt how to act now.
