Practical Life Hacking: A handbook of the most effective fixes for everyday problems

Practical Life Hacking is a guide of tricks, often called life hacks, which seek to solve problems in a clever way. You won’t need any expensive equipment or hard to find ingredients.
The book is divided into 9 chapters:

•Insomnia: how to sleep better, get rid of screen induced insomnia
•Digestion: how to improve digestion in a matter of minutes using only a fruit
•Testosterone: boost its levels 100% naturally (to TRT levels)
•Speed Reading: read at 400+ words per minute
•Hangovers: cure/prevent them even if you drink a lot
•Health hacks: cure headaches and sore throats instantly
•Unethical tricks: pranks and dark side hacks (use at your own risk)
•Minihacks: household tricks
•Productivity/Lifestyle/Mentality tools
Each chapter tackles a main problem that either one of us faced or we wanted to improve or fix. For each one you’ll only need fruits, vegetables, OTC minerals (like potassium or magnesium) and/or you’ll have to download a free app.

The hacks are very easy to do and require minimal preparation time. Give it a try; you'll learn a lot!
