More exercise on the menu
Taking into account the eating habits of most Canadians, new research shows that 60 to 90 minutes of moderate to vigorous exercise are needed each day to avoid weight gain and ensure that the heart and lungs stay healthy. This contrasts with the current 12-year-old guideline of 30 to 60 minutes a day. The next step in the research is to see if the exercise needed can be broken up into more doable 10-minute portions.
How much exercise do you manage to get each day?

Tweets in space
Flight Engineer T.J. Creamer used the new ISS internet software upgrade to send this message: "Hello Twitterverse! We r now LIVE tweeting from the International Space Station -- the 1st live tweet from Space! :) More soon, send your ?s". This is the first time astronauts are able to use the internet directly. Previously, messages were sent to Mission Control to be uploaded. Officials wanted to make sure the Space Station's computer systems couldn't be hacked from the net.

Less fitness, more fatness today
A recent survey finds that the fitness level of Canadians has decreased significantly since 1981. Using a number of tests in addition to body mass index measurements, the data shows that the body size of the average Canadian has increased. Given the association between health and fitness, the data is cause for concern since it suggests that the health of Canadians is in decline as our weight increases.
How are you maintaining or improving your current fitness level?
