This is what a "shalai" or "shabaka" looks like — a unique hybrid of a jackal and a Laika dog, bred specifically for work in the special services.

They have a super-powerful sense of smell — they can recognise up to half a million scents — and are remarkably hard-working, performing tasks in temperatures ranging from -70°C to +50°C. They are also 60% vegetarian, as this diet helps to keep their sense of smell sharp.

This is a young and very rare breed — there are only about 100 of them in the world.

Foul language in people is a sign of high intelligence, not the opposite.

Linguistic studies have shown that the ability to swear a lot and in a variety of ways indicates a rich vocabulary and developed fluency of speech.

It turns out that masterful use of profanity is not a sign of ignorance, but a complex communication skill and a sign of eloquence.

Disrupted sleep patterns significantly increase the risk of heart attack, dementia and depression, according to a study by the New York Times.

Irregular sleep disrupts circadian rhythms. The body becomes confused about when to produce melatonin and cortisol, metabolism is disrupted, immunity declines and chronic inflammation accumulates.

It's easy to fix this:

— Go outside every morning at the same time, for at least 20–30 minutes.
— If you can't go outside, use bright light or a lamp in the morning.
— Set your alarm clock an hour before bedtime and prepare for it calmly, without gadgets.
— Stick to your schedule even on weekends — a deviation of more than 30 minutes is already considered a problem.
— Don't wait until you get tired — the damage is done in the background, even when you feel fine.

Experts are confident that stable sleep works better than any biohacks.

The crew on board must constantly maintain the same level of load on the reactor to prevent it from stalling. Thus, nuclear icebreakers become true beacons in the world of endless polar night.

People with high IQs are more likely to be lonely and unhappy in relationships, according to a study.

Intellectuals often remain single because they think too much. Low impulsivity and constant cold calculation prevent them from igniting the "fire of love" and emotional intimacy in another person.

In addition, smart people are usually too demanding of their partners — it is difficult to find suitable candidates who meet their criteria.

You know who to send this to.
