 The following are some **statistics** about the Internet as of early 2020s: there are over 5 billion users world-wide (more than half of them from Asia and mostly young people), it is estimated 63% people worldwide use the Internet with the number being as high as 90% in the developed countries. Most Internet users are English speakers (27%), followed by Chinese speakers (25%). It's also estimated over 50 billion individual devices connected, about 2 billion websites (over 60% in [English](english.md)) on the web, hundreds of billions of emails are sent every day, average connection speed is 24 Mbps, there are over 370 million registered [domain](domain.md) names (most popular [TLD](tld.md) is .com), [Google](google.com) performs about 7 billion web searches daily (over 90% of all search engines).
 
-PRO TIP: **you should print your own offline Internet** (or maybe we should rather say offline [web](www.md)). Collect your favorite websites and other resources (gopher holes, Usenet threads, images, ...) and make a single dense [PDF](pdf.md) out of them. Process each page so that it's just plain text, remove all graphics and colors, unify the font, make the font small and decrease margins so that you fit as much as possible on a single page to not waste paper. For many pages, like Wikipedia, a small script will be able to do this automatically; the uglier pages may just be edited manually. An easy approach is for example to convert the pages to plain HTML that just contains paragraphs and heading of different levels, then copy-pasting this to LibreOffice, globally editing the font and auto-generate things like table of contents and page numbers, then exporting as PDF. You can even make a script that contains the list of pages you want to scrap so that you can make a newer print a few years later. Once you have the PDF, print it out and have your own tiny offline net :) It will be useful [when the lights go out](collapse.md), it's a physical backup of your favorite sites (the PDF, as a byproduct, is also a single-file backup in electronic form), something no one will be silently censoring under your hands, and it's also just nice to read through printed pages, the experience is better than reading stuff on the screen -- this will be like your own 100% personalized book with stuff you find most interesting, in a form that's comfortable to read.

You should also download your favorite and essential websites and other files for offline use, this way you'll be able to browse even when the Internet collapses and/or if you're just somewhere without connection, plus you'll have a backup in case they go offline themselves. Here is a [KISS](kiss.md) script template that does the downloading (it can also at the same time serve as a list of your favorite websites), also feel free to improve it (e.g. compress/minimize the downloaded files etc.):
