You may be 38 years old, as I happen to be. And one day, some great opportunity stands before you and calls you to stand up for some principle, some great issue, some great cause. And you refuse to do it because you are afraid ... you refuse to do it because you want to live longer ... you're afraid that you will lose your job, that you will lose your popularity, or you're afraid that somebody will stab you, or shoot at you or bomb your house, so you refuse to take the stand. Well you may live until you are 90, but you're just as dead at 38 as you are at 90. And the cessation of breathing in your life is but the belated announcement of the earlier death of the spirit. (Martin Luther King, Sermon, Nov 1968)
Enough said ...
