Talking points: Frogs legs on the menu, the dirtiest air in Europe and Web-surfing Canadians Everyone knows the delicacy of frog's legs is of French origin, right? Guess again, mes amis. The Guardian reports on a recent archaeological dig in the English county of Wiltshire that has unearthed evidence of frog's legs being eaten in Britain - and likely more than 8,000 years before they became popular in France. Conducted by the University of Buckingham, the excavation is being filmed for a documentary co-produced by the BBC, CBC and the Smithsonian Institute. Archaeologists discovered the bones of a small animal last summer and shipped it to the Natural History Museum, which confirmed the creature was once a toad and had indeed been cooked and consumed. "We were completely taken aback," said team leader David Jacques. They would have definitely eaten the leg because it would have been quite big and juicy. If you're going to Bulgaria, better bring your own oxygen. As reported in The New York Times, the Black Sea nation holds the dubious distinction of having the dirtiest air in Europe. A study prepared by the European Environmental Agency reveals Bulgaria has the highest concentration of the two major varieties of particulate matter - microscopic airborne droplets and gas particles spewed from smokestacks, car tailpipes and other sources. The stuff's been linked to a wide range of respiratory ailments, as well as cancer and heart disease. "Sometimes I do the following experiment," said Alex Melamed, a resident of the capital. I walk around in Sofia and do not touch anything. When I come back and wash my hands, the soap gets dirty. Following Bulgaria in the bad-air report card were Poland and Italy. Besides having the perks of hockey, health care and Tim Hortons, Canadians also surf the Web faster. CBC News reports on a study from PC Magazine that showed Canadians enjoy consistently faster wireless network speeds than our American cousins. Over a two-month period, experts surveyed the delivery speeds of Canada's big three wireless providers - Rogers, Bell and Telus - in over a dozen Canadian cities. The results: Rogers was fastest, followed by Bell and Telus. The bad news: We pay more for that speedy wireless service.
