DNA is the unique genetic fingerprint that makes us who we are. From its use in solving murders to its importance in parent testing in humans and animals, it represents a giant leap forward in science. The way DNA has shaped history fascinates me.

If “you are who you are” and certain things cannot be changed due to your DNA, does that also mean “you do what you do” and that every outcome is predictable?

In certain people, yes.

As a coach, my job is to guide and educate. Do I make a lasting difference? This is a question I expect all teachers ask at the end of a tiring day! Sometimes the answer is unclear; sometimes it is obvious.

Often, I watch my pupils compete and wonder whether I am seeing tangible evidence of anything I have taught them or whether I am merely witnessing what would have happened anyway. This is not me doubting myself; it is me trying to be objective so that I can refine what I do.

I am fascinated by what and how much information the human and equine brains are able to retain. But there is a big difference between the two: one is evolving rapidly in today’s high-tech society, while the other has changed very little in thousands of years.

How is harmony to develop between horse and rider when one has aims and ambitions and the other is happy eating grass? Is it possible to predetermine how both will do on their educational journey?

As if aging isn’t hard enough! Creaky joints, sagging backs, loose teeth, increased infections, poor digestion, and embarrassing gassiness -- just a few of the problems associated with getting older (for your horse, not you!).

But what was once a given in youth, now turns into a deficiency – vitamin C must now be added to the diet. You see, young horses are able to produce all the vitamin C they need for every-day health. This is why you typically do not see it added to commercially fortified horse feeds.

But as horses get up in years, they are less able to manufacture vitamin C. Decreased liver function is the main reason, but it can also be due to a decline in hindgut microflora and an increased propensity for pituitary dysfunction.

Why is vitamin C so important?

It prevents oxidative damage to your horse’s tissues and organs. In other words, it is an antioxidant. Antioxidants donate electrons to highly volatile, damaging molecules known as free radicals. Free radical production is accelerated during any type of physical or mental stress, muscle and joint inflammation, allergies, illness/injury, or exposure to toxins and pollutants.

But once free radicals receive their missing electron from vitamin C, they are neutralized – calmed down – and are no longer harmful.
