A Netherlands-based electronics firm is creating a bracelet that will change color and flicker from yellow to red when a person’s emotions rise to unhealthy levels. It’s being developed chiefly for stock traders on European exchanges. When trading becomes too intense and the trader’s blood pressure rises, the device will issue a warning to, “Take a time-out, wind down or reconsider their actions,” said the manufacturer. The results, hopefully, will be beneficial to investors—to say nothing of the stock brokers themselves.
