It’s Day 3 of #500Daysto50. I started this on Day 1, even though I’ve been suffering with a cold for around 10 days now. Honestly, it’s been getting me down more than a cold should. Why is that?

I’ll be talking much more – way too much more for some people – about acetylcholine (a powerful neurotransmitter), but we’ll start with an extra small dose now.

I suffer from an “above average” amount of acetylcholine in my system. (No reliable consumer-facing tests exists to prove this, but the evidence for that un-diagnosed diagnosis is super clear in my case.) That means all the regular symptoms of a common cold are heightened – runny nose, congestion, etc. In fact, most cold medicines contain anticholinergic properties, which suppress symptoms.

So you might understand why I missed a day, and you’ll hopefully understand that when I miss a lot of other days in this set of 500 posts, it’s almost definitely due to acetylcholine.

As I mentioned, lots and lots more of that to come…
