Just because you’re not required to go to school after a certain age doesn’t mean your curiosity and thirst for knowledge stops.

For those people who just can’t study enough, there are ways to expand your mind without having to pay hefty tuition fees or attend in-person lectures. With a lifetime subscription to CuriosityStream, the documentary streaming service, you can dive into multiple subjects anytime, any place. 

This award-winning streaming service lets you view documentaries, exclusive content, and original films on-demand with just the touch of a button. The immersive video experiences come from experts like David Attenborough, Michio Kaku, and Brian Greene, who lend their expertise and narration to the most interesting subjects, including nature, history, science, and much more. The best part is you can watch HD and 4K documentaries on multiple devices, and you can even download them to your device ahead of time to watch on the go without WiFi.

Since new content is added weekly, you’ll never run out of things to watch. The search function is built to find what you’re looking for as fast as possible through multiple search tools and easy title browsing. As you start watching documentaries, you can rate them according to preference and interest and new titles will be suggested to you in the future. It’s just like Netflix or Hulu, only you’ll always learn something new.

Normally, lifetime access to the CuriosityStream HD video plan retails for £182, since you’ll never have to pay monthly or yearly dues or additional subscription fees. But, for a limited time, you can get lifetime access to all of the content for just £108.81. All you have to do is enter code STREAM25 at the checkout to take advantage of the limited-time deal.
