@Lydie@tech.lgbt That’s why people with pacemakers or other sensitive medical devices need to stay away from microwaves. The microwave's 'shielding' isn't perfect; it can degrade over time, especially in places with frequent power fluctuations. And it’s not just that—in my case, the microwave clock at home would run faster than other appliances. It was more sensitive to changes in the electrical frequency, even without a noticeable fluctuation (like a brownout or power dip).
