I've been using computers regularly since around 1990, mostly Macs. Writing, graphic design, internet, database—the usual. Lately my wife has been asking me to clear my internet history before closing the browser to keep our DSL connection from bogging down. Does that actually help? I used Macs at work for years and never had to clear the history. I don't mind doing it and will continue to, regardless, for the sake of domestic harmony and because I don't really care. I'm just wondering whether it's good science or urban myth. Thanks!
