Of course, working dads deserve some leisure times too in the front of cable TV. Nothing is wrong with any dad watching TV. However, TV addiction sets in, when most of his free times are spent before TV. Then, that may not be recommended for a responsible dad. Spending too much time before TV competes with your free times to do some things you love to do personally to improve yourself as a dad.
While you may use some TV times to relax yourself after busy and tired work days or during weekend after a busy week, consuming too cable TV may increase lethargy and some bodily issues. You may be becoming inactive and putting more weight before you know it.
Also, spending too much time on TV may be sending poor role model lesson to your young children, who may pick up the addicted TV habits too. Remember, too much TV time is not good for kids either.
