5 years ago I started turning back to calligraphy, fountain pens, and hand writing. I buy books and fill up my bookshelf. It wasn't just for the memory recall, it was the pleasantness of writing.
I can't begin to tell you just how wonderful it is to write with a nice fountain pen. This was the culmination of writing instruments prior to the bastardization caused by modern cheap pens/pencils. I heartily recommend folks pick up an affordable Parker pen or similar and try it. It's also a great stress reliever to just free form thoughts onto a page, and you'll remember what your wrote later in the day!
One other bonus, your handwriting improves. I had to fill out some government forms recently. The online forms were cutting off any addresses longer than 24 characters, so I filled it out by hand. Went into the offices to submit and after the clerk saw my papers they went, "oh my goodness, you have incredible handwriting!"
Besides the learning, recall, etc, there are so many side benefits. Read and write physically y'all!
