So whenever I am done at my computer(laptop actually, late 2013 15' RetinaMacbook) for an hour or so I instantly feel this need to turn my computer off and power everything down to 'give it a break'. Is this actually necessary? Or is it actually bad having to power up my hard drives and stuff more than I need to. Meaning it would be better to have it continuously running as much as possible? Only reason I gravitate towards doing this is because I have a vivid memory when I was younger of my parents saying "get off the computer for a bit to give it a break" haha..so I've always had this idea in my head that computers need 'breaks' to pro long life. True or untrue?
