This Quora post raised a sad smile:

“Are there any climate change deniers left on the West Coast?

A woman believed she was dead. Her family took her to a psychiatrist. He asked “What’s the problem?” She said “No problem. I’m just dead, that’s all.”

He thought for a minute. “Do dead people bleed?” he asked. “Of course not,” she replied.

He sterilized a surgical needle, had her hold out her hand, pricked her finger, and squeezed out a bright red drop of blood.

She stared in amazement, then exclaimed “Holy cow—dead people do bleed!”

Does that answer your question?”
