Congratulations @dbooster !
Although I'm a few months away, at the end of November, I'll also be celebrating my 40th lap around the sun and the anniversary of my existence in this reality!
I'd never heard of Natto, so I did a little research into what it was. Then I looked it up on wikipedia and noticed that it is a traditional Japanese food that is made from the fermentation of soybeans by Bacillus subtilis var natoo! And that's where its name comes from... or maybe exactly the other way around, and it was the food that gave its name to the bacteria that was later identified!
But there is clearly a link between eating fermented, natural products such as Kimchi, Sauerkraut, Kefir, Kombucha.... So many options and it seems that they have even more benefits for the intestinal flora, which has already been proven to have a "link" with good brain function and the immune system. So the connection you make between drinking Nattō and daily physical exercise seems quite logical!
With regard to The Lord of the Rings, although I've only seen the movies and haven't read the books, I'm going to choose a character here to talk about the positive points I find in him. I'm going to choose Tom Bombadil. He's a character who shows an enormous connection to nature and a great joy in being able to communicate with the forest. As he has a more secondary role, he ends up being like Switzerland, and not linked to any of the factions, which allows him to be an observer of the whole story without taking sides straight away. His dedication to the Hobbits makes him a character who is often associated with kindness and love for others.
I hope you had a fantastic day with your loved ones!
