Things that take time, are good for you, and sort of free

I've got some perpetual objectives in my family: spend more time together, engage in healthy activities, teach them to care about other people outside of themselves. In context of the global recession somewhat, I have the following perspectives:

1. Teach our children to spend less time in front of a screen, whether it's a TV or a computer.
2. Teach them to be something more than consumers.
3. Teach them to spend more time in healthier activities.

"Monkey see monkey do". So it starts with us. Don't switch on the TV or computer until your kids are bed.

So my premise is: What are the things that will substitute the time spent in front of a TV and computer, that is good for you, and doesn't cost a lot of money, and you can do as a family.

1. Spend at least one night a week playing games. Not video games. Games. Monopoly. Card games.
2. Spend at least one hour per week, taking a family walk.
3. Go to the park, bring sandwiches, fruit and drinks. It's called a picnic. Once a month.
4. Find somewhere you can volunteer as a family once a month.

Don't just go to a movie. Don't just go to the mall. Don't just sit and watch TV. Break the habit. I guarantee you. If you do points 1-4 for 3 months, you will have a radically different family life, and you'll save money too! And have lost some weight to boot.

Can't lose.
