Okay... 1-4 and 6 are understandable, 9 yes, mental inactivity encourages dementia, people shouldnt just be watching TV, especially past a certain age, if you dont use it you lose it.
5 is not really a habit, but I guess it could be damaging?
I'd like to see some expounding on 7, 8 and 10, not really undestanding the logic there.
