Which thread direction for bottom brackets?

Unless you're a professional spanner, you're probably like me and get confused which way certain threads loosen and tighten on your bike. The pedals and bottom bracket each have a side that threads in in reverse ie tightens anti-clockwise and loosens clockwise. To make it even more confusing, pedals threads and bottom brackets threads each have a different 'wrong way' thread!

I was inspired to create this post when I came across a statement on the internet that suddenly make it easy to remember which way English threaded bottom brackets thread in and loosen - each side tightens towards the rear of the bike - simple!

The drive-side of the bottom bracket tightens towards the rear of the bike which makes it the unconventional thread:

The non-drive side tightens towards the rear of the bike which makes it the conventional thread:

It's easy when you know how! It's now easy to remember which way pedals thread into the cranks - they tighten towards the front of the bike ie the drive side has a conventional thread while the non-drive side has the unconventional thread.
