Gravity Strikes Again

Why do your feet swell during aeroplane flights? It’s not sudden-onset elephantiasis (probably).

Instead, it’s due to blood pooling in your veins. (As blood tends to do when stationary, thanks to gravity.)

Yes, gravity strikes again!

The Persimmon Principle

As delicious as they might be, persimmons can cause a phytobezoar. This refers to an indigestible clump of fibres that can lead to intestinal obstruction. (Everyone’s least favourite thing, unless you’re super weird!)

That’s an uncommon complication from eating too many of this fruit, not that eating fruit is inherently a bad thing.

Luckily, persimmon phytobezoars can be conquered with Coca-Cola.

It’s drinks such as that which, under normal circumstances, contain an excess of sugar. That’s in contrast to fruit. Ironically, in this case, the roles of causative agent and cure have been reversed.

Plaster Makes Warmth

After you apply some wrapping around wet plaster, you might notice that the patient’s limb feels warm.

Is this simply a product of insulation?

No, it’s not just this reason.

It’s primarily because plaster and water form an exothermic reaction, so heat is released.

People can be burned by this!
