I have just finished reading the online local newspaper of my mother's small town. A caregiver, aged 74, and known by relatives to be exhausted, fell asleep at the wheel of her car and wandered into the adjacent lane where the traffic was going in the opposite direction. She died in the resulting collision as well as the 25 year old woman in the other car. This is so tragic - someone who had good intentions, just pushed beyond her strength.
Everyone would like us to be superhuman and sometimes so would we. But we are not.
