I've watched TV since I was probably less than a year old and it has probably done as much for me if not less than Graal has, but I still watch it occationally so I could say I've watched TV all my life. It does not mean I don't have anything else going on.
The idea to judge if someone has a 'life' based on one activity or hobby is tiresome. It's as if people don't wish anyone else to have long standing hobbies.
