People of North Russian know that eating raw food, or better to say as it was in nature, can be very beneficial to your health.
The only problem is that the food available during long polar nights in raw state in these lands is meat and blood - the flesh of the freshly killed deers they breed. So, they eat it as it is - raw and uncooked. People say, that this is the only source of vitamins, especially vitamin C for them, and due to this habit they maintain to survive in severe Northern climates for hundreds of years.
Children participate in such bloody lunches since the early age and perceive the taste of raw flesh and blood in no other words as “Tasty! Delicious! Awesome!” or even “The best thing to eat in whole life”.
