Nature also demands that we breathe.
A raindrop doesn't go into therapy, call a committee or debate to figure out which direction to fall.
More was learned from the fall inward than by trying to be pure.
Our bodies are designed to be successful. Our minds are tools to discover ever-more principles to enhance this success and to advantage others.
Nature handles death.
Religions use it as a means of leverage.
The dead don't care about us in the ways that we think they do.
