Q. My mother is older with mounting medical problems. I'm worried about her living alone, but I don't want to hurt her independence. Is there a way I can keep an eye on her remotely?

Do you need a smartwatch?

Q. What does a smartwatch do exactly? Will it replace my smartphone?

A. There are actually several kinds of smartwatches. A few like the Moto 360 and Samsung Gear Live include cellular so they can be smartphone-independent. However, given the small screen and slow processing, they aren't true smartphone replacements. Other options like the Apple Watch and LG G Watch R require a smartphone to do most tasks, including making phone calls and sending texts. The gadgets connect over Bluetooth to display notifications and communications, send back health information like your heartbeat, and do some basic smartphone controlling. Consider smartwatches as enhancements for your smartphone rather than replacements. Here's a handy chart showing how some of the smartwatches currently on the market stack up.

See every Google search you’ve made

Q. I heard you say on your radio show the other day that Google records every search I make. You told us how to erase it, but I don't remember. Can you tell me again?

A. Google does record everything you search for, along with everything else you do while using Google services, programs and apps. To see and clear your search history, go to history.google.com and sign in. Then click the Gear icon in the upper right corner of the page and choose "Settings." Move the slider next to "Your searches and browsing activity" to the left.

Google will ask if you really want to pause recording. Click the "Pause" button to confirm. Of course, that's just the search history. Find out how to see every piece of information Google has ever recorded about you.

A. Windows doesn't always do a good job of removing every trace of software you no longer want. Fortunately, there are third-party programs that do. Check out powerful free programs like Revo Uninstaller and GeekUninstaller. They pick up what Windows leaves behind.
