I‘ve been actively walking during my lunch breaks, when I get home, and on the weekends. I do about 6-7 miles a day. I find this paragraph to be very true .. I‘m a native Californian and moved to Minnesota 6 years ago. When I walk in the winter I feel more invigorated than any other time of the year! I also feel I do better at work (focused more), and can accomplish more. I‘m almost 40 and feel like this is the most energized I‘ve ever been.
