The internet gives me anxiety.

Living in a house that is approximately 100 years old has recently led me to develop a concern for carbon monoxide poisoning. In an effort to gain a more thorough understanding of the matter, I googled it. And this is what I found:

     Depending on the degree and length of exposure, carbon monoxide poisoning can cause:

1. Permanent brain damage.
2. Damage to your heart, possibly leading to life-threatening cardiac complications years after the poisoning.
3. Death.

Great.
