I don't think watching TV is a big waste of time for following reasons.
Reason 1 .My grandparents had no TV. They had 12 children. I don't want 12 children
Reason 2 . Watch David Attenborough's masterpiece planet earth.
Reason 3. I just watched the world cup on TV just gone and experienced the same highs and lows as my grandparents did when they found out they were having yet another child.
Hahaha
