In business, my head needs to rule over my heart.

What people fear most about tragedy is its randomness - a taxi cab jumps the curb and hits a pedestrian, a gun misfires and kills a bystander. Better to have some rational cause and effect between incident and injury. And if cause and effect aren't possible, better that there at least be some reward for all the suffering.

When someone gives 60 days' notice, they're able to play an active role in identifying and training their replacement.
