Although the majority of university students may not read books for pleasure – as proven in Japan for instance , or do not read at all  – if that’s what really happens , and there is no clear yes-or-no answer whether students learn as much when they read digitally as they do in print , reading books should be your personal development priority in life, in general, as you are likely to live longer when you read, reading books can help you be more open-minded and creative , it can be good for your mental health (or the lack of it may be very devastating, as a matter of fact)  – and last but not least, as former POTUS Harry S. Truman allegedly stated: “All leaders are readers.” 
During the first ten years after Amazon launched its first Kindle e-book reader in 2007 , a rapidly growing percentage of reading activity had been conducted on e-book readers, then, around 2016/2017, the trend has taken an unexpected turn , and physical book sales started to rise again , for a number of relatively obvious reasons (which nobody would have predicted with certainty in 2007), such as: print books smell good, last longer, make more meaningful gifts than e-books (as they are more tangible and memorable than a simple electronic file download), they are more easily shared, they can be can be more easily scribbled in and marked up than an e-book, and last but not least: reading print books sets a good example for children  who are more likely to recognize a print book because its physical format than as content on a screen, which is also true for readers themselves who recall less of the contents read electronically, than that of print books .
The proverb says it all: you don’t know what you have until it’s gone. Apparently, readers had to experience the difference between e-books and print books before they could truly appreciate the value of “old-fashioned” reading, for themselves, and future generations: shared book reading is an amazing developmental activity to engage in with children , and these reading experiences can set the stage for later reading success .
Surprisingly enough, members of the so-called millennial generation – meaning “anyone born between 1981 and 1996 (ages 23 to 38 in 2019)”  who have grown up in the age of technology are more likely to have read a book in the last year than those over the age of 30 .
HOW you “consume” books, certainly says a lot about your intelligence  and your general learning process, in various ways. Are you a bookshelf overstuffer? Do you do so-called “fractal reading”? Do you abandon books often? How many unread books do you have?
The bottom line is: even though books certainly make great graduation gifts, there may be funnier, cheaper, and more personal ways to surprise a graduate, who has spent the last few years of his life reading a lot. How about a t-shirt, a coffee mug, a tumbler, or a notepad (for writing!), with an inspirational design?
