"Your light switches can be doing a lot more for you than just turning things 'on' or 'off.' After reading about it on Reddit (and writing a BuzzFeed post including it), I personally replaced the standard light switch that controls my bathroom fan with one that has a built-in timer. For 10 minutes of work (and about $25), it's become one of the most luxurious features of my home, and I honestly just want everyone to do the same. Swapping out light switches is way simpler than you think!"
