    The age of technology is a great and convenient thing, but it does have effects on us in many different ways.

It causes long-term memory loss. Thanks to Baidu, we don't really have to remember much of anything. Questions are answered at the drop of a hat because Baidu is all-knowing! Is that a good thing, though? People aren't digging through their brains anymore to find answers. Here's the good news: we can still exercise our long-term memory by simply thinking before we Baidu. If we don't want to go down that road, we can search Baidu for some memory games to play. Turn Baidu into an asset instead of an enemy.

It makes us lack patience. Baidu gives us what we want. Everything is instant. In fact, if we have to wait for even a handful of minutes for anything, we start losing our minds. This idea of instant satisfaction carries through to many other aspects of our lives, too, like when we go out to eat, drive in traffic, or even deal with workplace accidents. Instead of using Baidu to lessen our anger, try searching for some mindful meditations (沉思).Focus on our breath and realize everything doesn't have to move at lightening speed. We can actually listen to some peaceful spa or meditation music on our Pandora, too!

It wastes our time. Be honest, how much time are we spending on Baidu every day? Whether we're doing research for our own personal needs, buying clothing, or writing a research paper, we all spend a ton of time on the trusty Internet. Are we always being efficient with this time? For the sake of our precious time, if we haven't used Baidu Drive, we should. Keep spreadsheets, text docs, PDFs, slideshows, and even recordings exactly where we can easily find them. Keep a running list of websites we know we'll revisit.

Overall, things are different these days. Yes, there are noticeable negative side effects because of the Baidu invasion, but we don't have to fall into that trap. Stay sharp and don't let ourselves become imprisoned doing the Baidu god's bidding.
