Diabetic Emergencies

Do the following things, in this order of priority.

  • Dehydration – rehydrate with IV fluids
  • Insulin – to combat hyperglycaemia
  • Electrolytes – potassium shifts are a concern

A simple acronym solves everything. The point is not to let the patient DIE.

The Sad Evils Of Smoked Salmon

Smoked seafood has, unfortunately, been cast into the same category as preserved meats. These traitors have been linked with an increased risk of malignancy. Shun them all!

On the plus side, chicken is still in season(ing). As long as you’re not a greedy pig about it. Moderation, which basically means not over-gorging, is the key to success. That is, health.

Settling The Contradiction In Urination Theory

Conventional medicine teaches that the parasympathetic system, through its powers on detrusor muscle contraction and internal sphincter relaxation, leads to micturition. Meanwhile, the sympathetic system does the opposite so the bladder does not push that sweet, gold urine out but holds it in.

Why, then, do people urinate more when they are nervous?

The pontine micturition centre is indeed an important area, one that struts around like a pompous turkey with its chest puffed out, wearing a mauve suit and a top hat. It certainly affects the desire to urinate. However, it is tempered by the all-powerful prefrontal cortex. That old dog!

The trusty prefrontal cortex: this fine specimen of modern decision-making prevents you from running yellow liquid down your leg, however surreptitiously you think it might be happening, while making small talk at a cocktail party or waiting in line at the post office. In short, it keeps socially inappropriate things from occurring at socially inappropriate times.

When the brain is racked by fear, the prefrontal cortex shuts down just a little, despite that possibly being the time you need it the most. No matter, because logic is replaced by emotion!

When the inhibition goes, so too does the bladder.

Positive Psychology 101

Nothing is real unless it exists in the outside world.

Your thoughts are not real. You cannot control them. But you can control the environment that affects them.

You cannot control where a dog urinates during a friendly neighbourhood walk. Will it be on the stump of a tree today? Or will it very coincidentally be under the letterbox of the old man across the street you do not particularly like? You cannot precisely determine this, even knowing it would almost certainly occur at some point during the stroll, but you can create lessons and precedents to influence what is considered more acceptable and what is considered less so.

Your thoughts are a wild farm animal zipping around in a fenced paddock. In a particular instance, the beast runs where it wants. At any given moment, you cannot decide exactly where in that enclosed field the your thoughts are. This level of microscopic precision is out of your control.

However, by maintaining an environment conducive to the kind of thoughts that you would like, you can control the dimensions, the weather and the general disposition of that paddock.

It is okay to be human.

Humans cannot control their exact thoughts but, over time, they are very good at meddling with man-made objects and putting artificial restrictions on things.

This is positive psychology 101: you can influence the world around you in order to become less of a grump.
