“For three decades the goal of tech development has not been to improve our lives or serve the public good, but to maximize shareholder value & increase the power of the companies that control it..the root of so many of the social harms that the tech oligopoly have saddled us with”@parismarx.com
For decades, Canadians eagerly rushed onto US tech platforms and services. But now the drawbacks of that dependence are on full display.

Conventional wisdom holds that caffeinated coffee is proarrhythmic.
However, a recent study tells a different story: consumption of caffeinated coffee averaging one cup a day was associated with less recurrence of AF or atrial flutter.
