I was surprised to see that this was the only comment specifically calling out loneliness (and although you didn't call it out by name, depression). Maintaining a social life takes work, maintaining one into your 70s even moreso; particularly if certain sacrifices which were seen to be necessary at the time were made to raise children who later leave. Divorce is more common than 40 years ago (I'm not taking a moral stand here, I'm all for leaving toxic relationships but friends are often lost as collateral damage), and grandchildren less. Social media and television are to our social lives what fast food is to our need to eat. I'd speculate that if you normalised for loneliness the screen use by age would become a much flatter line.
