I have a dog and walk her twice a day a mile each walk. Sometimes it wipes me out though. I try my best to stay active. I have a dodgy heart which seems to come with this wonderful condition. I am also vegetarian and try my best to eat as healthily as I can when I am up to standing in the kitchen chopping all the veg.
Wow, you can do a mile twice a day?! I'm impressed (and jealous.)
I have a dog as well which is how I get in the 15 minute walk each day!
