Question: Do you believe in ghosts?

Carolyn Nielsen answered on 17 Nov 2015:

Nope! I did listen to a really interesting podcast recently though (from the This American Life series) about how carbon monoxide poisoning can cause hallucinations and weird sensations on your skin… so ‘symptoms’ similar to what people report when they live in old houses (with poor ventilation and old heating systems!) and claim they are haunted by ghosts. So if you know anyone who thinks their house has ghosts, strongly suggest they get a carbon monoxide detector because carbon monoxide leaks are actually really dangerous.
