Home Schooling (Dolphins)

Home schooling can be quite a challenge sometimes, but it was an absolute delight learning about dolphins with Matilda (4). The task set by her teacher was to watch a video and then answer some questions in an online worksheet.

Dolphins sleep with one eye open, because they sleep with only one half of their brain (in four hourly periods). This is so they can keep on breathing and not drown; I needed to explain to Matilda that they’re mammals and not fish. It also ensures they can look out for danger, keeping their muscles working to maintain their body temperature. They also have their own name, watch the video! They can’t smell, but do use echolocation to identify dangers before they can see them.

We also learnt that dolphins eat fish, squid, and octopus, amongst other things, to which Matilda replied, “But octopus don’t like being eaten.”

Note: While learning about sleeping with one eye open, I couldn’t helping thinking about Enter Sandman by Metallica.

Food Supplements and Vitamins

They say that if you have a good, balanced diet you don’t need food supplements and vitamins. Now, I’m not a doctor, but I feel there is a place for them at times and in certain circumstances. I’m only making personal suggestions here, so it’s important that you use common sense, and seek medical advice if necessary because there can be adverse effects if taken inappropriately.

Because I’m over 65 years old, I take a number of food supplements and vitamins daily: a multivitamin and mineral tablet (formulated for men), a glucosamine and chondroitin tablet to protect my joints (especially as I’m a runner), an omega 3 fish oil capsule (unless I’ve eaten oily fish that day) to help maintain a healthy heart, and a vitamin D capsule.

Vitamin D is essential for the optimal performance of our immune systems, and is produced naturally in the body with the help of sunlight. Unfortunately, it’s easy to become deficient in this sunshine vitamin in the UK and other countries with short days and little sunlight in winter.

A few years ago I was diagnosed with a vitamin D deficiency and was prescribed a high dose of this vitamin. I now take a high daily dose of vitamin D in winter, and a maintenance dose during the summer. In the current coronavirus pandemic, it might be worthwhile thinking about taking this vitamin, but please take medical advice as you can take too much.

Each of my young children also have a daily chewable age-appropriate multivitamin pastille, and they always remind me at teatime in case I forget.

Do you take food supplements and vitamins?

Silver (Walter de la Mare)

The_phase_of_Moon

Slowly, silently, now the moon
Walks the night in her silver shoon;
This way, and that, she peers, and sees
Silver fruit upon silver trees;
One by one the casements catch
Her beams beneath the silvery thatch;
Couched in his kennel, like a log,
With paws of silver sleeps the dog;
From their shadowy cote the white breasts peep
Of doves in a silver-feathered sleep;
A harvest mouse goes scampering by,
With silver claws, and silver eye;
And moveless fish in the water gleam,
By silver reeds in a silver stream.

Walter de la Mare (1873-1956)
