Brain Action

I just read an article on the web that says that after you die your brain is still working for a short time and can formulate thoughts. Really? Now I am upset. Who needs my brain to keep working? I have spent my entire life thinking and worrying 24/7. I was hoping that death meant an immediate brain tune out. At peace. At rest. Finito. Now I have to look forward to still thinking even after I die. Thanks a lot.
