Health is a class usually presented in most public schools, basic hygiene, sex-education, disease prevention, etc.
Healthy living/eating is usually taught by parents and controlled by the same.

TO continue:
Merely having a digital device does not make one "smarter" or increase their IQ level.
Much of those devices, especially the portable ones, phones, tablets are responsible for taking people skills of social interaction out of the equation.
People are so enamored by and glued to their devices that they are and have been putting themselves and others at serious risk.
Some have been so busy texting, typing to each other and various social media sites that they have fallen down stails walked into posts, poles, subways, and traffic. Some have even stepped into open manholes and face-slapped signs while "distracted".
Pretty bright aren't they?
The devices do not make people smarter. It enhances their ability to obtain information more quickly than ever before.
Most Public Libraries are not the same large facility full of shelves crammed with books of all kinds. Now we can order any book we need online and have it the next day or two without driving, parking, hunting through that Dewey Decimal Card Catalogue to see if the book you want has been checked out or if it's still on the shelf, waiting in line, driving back home. Only have about 2 - 4 weeks to read the book and return it else pay a fine.
Nope, most libraries are now re-branded as Community Media Centers. Some still have books but also a large number of card readers, CD's, DVD's, Books on Tape, Regular old fashioned Books and social rooms for small children, teens, adults, catering to all likes and needs. Smarter? Not really, but certainly more in keeping with the times and more diverse.
We are smarter in the way we've fashioned tests to make ourselves seem smarter, largely due to these changes.
Some call it "The Dumbing Down of America or society in general" - Let's make the coursework or testing easier so more students pass the classes and we look like we're providing a better standard of education!
I'd wager the average high school student could not pass an 8th-grade test in 1895 or 1912. BTW, no computers or calculators nor Internet allowed.
Here's one from 1895
