It’s mainly the correlation effect and vagueness. They arent drawing any conclusions they are just implying conclusions. Ie They did a survey of how much time.people spent watching TV. They saw that the more time watching TV was linked to a higher obesity rate. And tons of studies linking obesity to shorter life expectancy. So watching TV can lead to a shorter life expectancy as a generalization. Take everything with a grain of salt these days. Key word here is “can or could”. I could make any bs claim if I used those two words. Like eating veggies every day could kill you (you can choke on brocolli and die).

Being sedentary is bad for you, and TV encourages people to be sedentary. You’d see the same negative effects if you sat and stared at a wall.
