This section is all about how to be healthy, cheerful, and fresh. Here you'll find out how to give mouth-to-mouth resuscitation without getting punched in the nose. You'll learn how to remove your appendix if you don't need it anymore. We'll also explain how to make gypsum, glue, penicillin or even all three together from scratch. Believe us, all of this knowledge will come in handy in the ruins of the post-apocalyptic world!

The whole world is a big chemistry lab and the only limit here is your lack of knowledge. If there's sand under your feet, you can make glass. If you see trees around you, it's a step from there to making paper. The magic of our civilization, which is electricity, can also be made from easily accessible materials. There are tons of ways to make it and we'll reveal the most original one.

Researchers have concluded that human brain development was always influenced by laziness and greed. We want to have as much as possible with minimal effort and that's what makes us geniuses. Mills and water pumps will do the work for you. The combustion engine will help you in traveling any distance. Cameras made of boxes and paper with photosensitive surfaces will immortalize your successes.

In all the worlds of the Multiverse in which this book will be published, we've agreed that killing people isn't cool. We wish these inventions never appeared, but still….The trebuchet is pretty darn good. To create saltpeter, which is the main gunpowder component, all it takes is hay and human urine. How long will you have to pee in the pit full of hay? You'll find this out in The Ultimate Guide. By the way, did you know that the alchemist who discovered gunpowder thought he was creating the elixir of life? Well, if you throw pots full of gunpowder at your enemies, you'll become immortal (for a while).

The home of ancient man began from fire, so if you don't want to be dumber than your ancestors you need to learn how to use flint and steel. If all goes smoothly, you'll be able to build a log house, weave a rug, mould houseware out of clay and build a boat. You'll learn the art of tying knots and using natural dyes. But above all, you'll learn how to construct a unique top-class mousetrap, so rodents won't have any chance. (Failing to do that, read about cat domestication in the Farming section.)

It's said that wheat domesticated humans rather than the opposite. Agriculture made us who we are today, so in this book you'll find a detailed description of grain types and animal farming principles. You'll learn to make fishing nets, help to deliver calves, procure salt and honey. But first you should learn to brew the best-ever wheat beer. (Which will literally be the best beer in the world since you'll be the only brewer after the fall of civilization)

Life is not only about surviving; it's also about not dying of boredom. There will be fewer fights in your survivor camp if you give people cards and chess. Your children won't set fire to your house (built thanks to the instructions of the Hearth and Home section) because they will be playing ball or flying a kite. You'll become a local movie mogul if you make a phenakistiscope, a device that creates the illusion of motion. By the way! We'll tell you how to make a vibrator.

There is nothing similar to the sound of the Australian didg. It's literally the voice of spirits. This musical instrument exists in all the worlds of the Multiverse, so make sure to read a manual on how to make it. The same applies to the jaw harp, which can be found in the history of any nation on the earth and beyond. During your interworld journey a sitar and a bell will come in handy too. Tell whomever you meet about the music theory of our world and don't forget to ask about their notation too.

Rituals, traditions, and etiquette are as significant as mechanisms and materials. The most basic and peculiar inventions of human communication were collected in The Ultimate Guide. How do you tie a tie to make a good impression? What is the philosophy behind fashion? What are the rules of setting a table and marking the road? How exactly do you carry out seppuku in the way that will most impress others?
