Some reassurance. A reader writes:
The article lumps together passive screens (televisions) with interactive screens (computers and/or video games). The difference between the two are so endless that any conclusions drawn that combine them are of suspect value. It's certainly possible that interactive screens are still a problem, but the difference in brain activity and social interaction between a TV and the Internet is hard to overstate.
Not to worry, mate. The article says "two or more leisure hours a day sitting in front of a screen"(emphasis mine). I expect you’re off the hook; by your own admission, you don’t have any leisure time.
Get well soon.
