This summer we got a puppy. And the interesting thing about puppies is that they don't really have a concept of time. I could come in at the end of the day and the puppy is excited to see me, wagging her tail and weaving in between my legs for contact and comfort. The same reaction could happen if I'm working in another room for a bit and rejoin the puppy and family wherever they are. The puppy doesn't distinguish between an 8 hour or a 20 minute absence. Our kids are a little smarter than the dog, although sometimes I wonder? And they have a slightly better concept of time. But they will still ask to go outside and play with their friends minutes before we're due to head out the door for a family function. Or after pajamas and brushing their teeth they'll ask if we can start a movie. But puppies and kids can be excused if they don't know time or how long things should take. Adults however know what an hour is, how long things take and how to manage their day. When it comes to exercise a common challenge is making the time to be active. We might assume that for a health goal to be realized requires a certain amount of daily fitness to achieve it. Intuitively I would guess most people think they need to exercise an hour a day. Now there's nothing wrong with training an hour daily. And if you're already in the habit than definitely keep going. But for those that aren't that active and haven't gotten started yet because they haven't carved out those 60 minutes per day, a new study should give them hope. The study was part of the Framingham Health Study and included over 400 participants....
