You’ve all heard surely of the little blue pill. But are you familiar with the little black pill?

Well, I’m here to elucidate.

Often left unloved in fruit bowls the world over, this humble fruit which has little pretensions, can be transformed into a Parkinson’s superfood, rich in dopamine, by simply freezing them.

The effect is virtually instant.

Bite into one these wonder fruits, and the injection of frozen grape juice will instantly lift your mood.

If it doesn’t, I shall eat gravel from my front garden.

And who doesn’t need such boosts in these stifling times, literally and metaphorically.

The extended heatwave is like being unable to eject a sweaty guest who has overstayed their welcome.

I’ve been trudging about the house who has been guarding his air cooler like a new pet.

We need a new word for “freezing”. It doesn’t quite work in 92 degrees.

Just keep those grapes handy.

Here’s the science bit:

Dopamine Release: When the grape melts, the cold activates TRPM8 receptors. According to insights on Healthandme.com

⁠Health and Me, this initiates a pleasurable sensory response that prompts the brain to release dopamine. [1]

And I’m still not convinced about levadopa, whether it’s side effects are a price worth paying.

I’m going to seek alternative.

Now some bonus poetry:
