Only 92 Minutes of Exercise needed to Extend Life

- Adam Clare

Researcchers have done something great for us lazy people: figured out the bare minimum amount of exercise needed to extend your life. The short answer is 92 minutes per week or 15 minutes per day.

Here’s some detail:

Compared with individuals in the inactive group, those in the low-volume activity group, who exercised for an average of 92 min per week (95% CI 71—112) or 15 min a day (SD 1·8), had a 14% reduced risk of all-cause mortality (0·86, 0·81—0·91), and had a 3 year longer life expectancy. Every additional 15 min of daily exercise beyond the minimum amount of 15 min a day further reduced all-cause mortality by 4% (95% CI 2·5—7·0) and all-cancer mortality by 1% (0·3—4·5). These benefits were applicable to all age groups and both sexes, and to those with cardiovascular disease risks. Individuals who were inactive had a 17% (HR 1·17, 95% CI 1·10—1·24) increased risk of mortality compared with individuals in the low-volume group.

Happiest Commuters Walk or Cycle to Work

- Adam Clare

Many cyclists can go on for hours about how great riding a bicycle everyday is (I know I can), and it has been proven that walking can make you happier too. It comes as no surprise then that walking or bicycling as your preferred commuting solution makes you happier.

What is surprising is that this conclusion of happy commuting comes from Statistics Canada!

Two-thirds of cyclists said they were very satisfied with their commute. Only 6 per cent were dissatisfied, according to a Statistics Canada survey of more than 6,000 people across the country.

It’s a striking difference from their car and transit-riding brethren. Only 32 per cent of drivers and 25 per cent of public transit users were very satisfied with their trip to work.

Brazil: Wind Power Now Cheaper Than Natural Gas

- Adam Clare 1 Comment

In Brazil a recent energy auction has shown that wind power is cheaper than natural gas in the country, and also a better investment opportunity. The competitiveness of sustainable energy sources continues to impress everyone (even with the subsidized resource-extraction industries), it’s only a matter of time until other sustainable energy options get this cheap.

They even expect the cost of wind power to decrease in the coming years!

EPE president and chief executive Mauricio Tolmasquim said the auctions show that wind and natural gas are competitive, predicting wind prices will continue to fall in Brazil.

“That wind power plants have been contracted at two digit prices, below 100 reals per MWh, showcases the energy market competition through auctions,” he said. “That wind power could reach these lows versus natural gas was unimaginable until recently.”

The energy auctions for a total of 92 projects were the first in Brazil for 2011, and also featured biomass, hydro-electric and natural gas projects.

Investments amounted to 11.2bn reals in total, for 3,962MW of energy that is slated to start generating in 2014.

Organic Fertilizers Cost Effective and Better for Crops

- Adam Clare

Here’s a good story about how poor farmers in Kenya have shunned expensive chemical fertilizers for cheaper organic ones.

The organic fertiliser is sprayed onto maize two weeks after planting, and a month later.

Kenya Plant Health Inspectorate Services through Kenya Agriculture Research Institute have tested the fertiliser’s components and given an analytical report.

Mr Mosbei said the use of organic fertiliser, apart from rejuvenating soil quality, saves farmers about 70 percent of the cost of production.

“Whereas it takes a farmer in the North Rift 100kg of DAP and 50kg of top dressing to plant an acre of maize, all they require is only eight litres at Sh300 per litre for the same acre,” said Mr Mosbei.

“The organic fertiliser enriches the soil with minerals and maintains an ample PH level for the minerals required by plants for optimum yield,” added Mr Rono.

Jack Layton 1950-2011

- Adam Clare

Jack Layton passed away this morning and I feel that in his passing we need to remember all the good that he has done for Canada. Obviously, it is in no way a good thing that Canada has lost such a strong and inspiring leader, but it is up to Canadians now to keep his momentum of positive change moving forwards.

To me, Layton was a beacon of hope in a rough political sea that used dirty tactics and horrible policies to further confused political or ideological goals. Layton always relied on honesty, facts, and a commitment to the betterment of all of Canada to get his political goals met.

Under his leadership the NDP gained historic victories against a rising tied of overtly hostile Conservative recklessness and a growing apathy about Canada and Canadianism amongst the people of Canada. Throughout his political career from city councillor to federal opposition leader he spoke passionately about his beliefs and lived up to them. He inspired many young Canadians to get into politics and to be passionate about their beliefs. He encouraged people to stand up for what’s right; to champion the causes of the downtrodden, the oppressed, working families, the environment, the right to a good education, and all other causes of social justice.

Indeed, if Layton wasn’t around to lead the NDP when he did I fear what Canada could have become. It is now up to all Canadians to carry forward the torch of positive change and to champion social justice. As Canadians we need to live up to what Jack Layton wanted Canada to be: a caring country that espoused respect and honesty within and outside our borders.

We have lost one leader in Canada, but we must not forget all the good that Layton has done. We need to remember, we need to keep makings all things good.

The CBC has a good obituary on his political career.

Edit: Layton’s final letter to Canadians can be read after the break:
