I have decided to go back to wearing hiking shoes instead of walking shoes. I can get a good pair for the same price as walking shoes but they last a lot longer because they are designed for long distances with lots of weight being cared. Unfortunately I have plenty of extra weight to care around... but I'm working on it! It's all part of my live better plan. The walking not only gives me exercise but I'm not paying a bloody fortune in gas .... the shoe leather is definitely cheaper then the gas. Even if I had to buy a new pair EVERY month it would be cheaper.
Walking does more for you then Exercise and save gas...
Walking your kids to school give you more time to talk to them about things going on. If you don't know what to talk about being out doors gives you lots of topics to discuss. Such as HEY do you see that Blue Jay? or What do you think of Joe the neighbors flower bed? Isn't walking in the snow fun? ...
I guess that one is probably only me.
If your older kids object to you walking with them then take along the dog (if you have one). This way they can always say they love walking the dog on the way to school but need you to take him home.
It can also make your neighborhood safer. If more people were out walking the less chance for criminals to scout out targets and break into homes. They work in private and don't want your eyes spying what they are up to.
That being said ... The more people walking outside between 7 to 9 and 2 to 4 the safer the neighbor hood children are from the scum that prey on them. More eyes means less chance of a grab. You don't have to be a parent to keep an eye out! If your retired or a stay at home parent and getting a little bored have a new purpose and walk the neighborhood. You get the chance to meet new people and improve the quality of life for all. Just from taking a walk.
