Why not if you have uninterrupted power supply. I have uninterrupted power supply most of the year and I switch off my PC less than 1 times in 2-3 months or maybe even once a year. And it always has got something to do with hardware or powercut.
And anyone can do it. I am sure quite a few others here do it too.
