Insensitivity?

I have always marvelled at our insensitivity. Whenever we hear of some pain, suffering or sadness we get considerably moved but after some time when the moment is gone we return to my normal life and do nothing much about those things which barely some time ago had moved me so much. This continues till the next tingle comes along but after that the cycle just repeats itself. I wonder if its plain laziness or inertia but whatever it may be it restricts us as human beings and lowers us if nowhere else then in our own eyes. What do we do about it? Guess the best thing is “Start Me Up”
