Or maybe your father had an addictive personality that he had dealt with in the past before having you, and he wanted to nip it in the bud in case he had passed it down to you (yes, addictive personality is heritable)
Nope, he does not have any addiction that I know of. He can easily pass time without doing things he mostly does and enjoys. His decision mostly stems from other parents (his friends) suggesting him to cut TV.
