During the month of May, Dr. David Suzuki issued a challenge to get outside and do something (not sit on your ass with a beer) for those 30 minutes for 30 days. I decided to take up the challenge at a time of the year where there is all kinds of yard work to be done. I have been outside doing something everyday since the beginning of May for a minimum of 30 minutes. I walk my dog, play with him, pick up out in my yard, walk for no reason, get in my pool and swim for 30 minutes.....lol the dog ends up joining me lol ( I think the weight loss is the skin he has clawed off me with his claws) I am sleeping better at night, I go to bed earlier, I eat a healthy breakfast, I do NOT eat at McDonalds.........ever, take a long hard look at what you are eating there, disgusting. I am losing weight and am much fitter (better sex is a benefit ). Like Nike says, just do it !
