I use candles in the evening to get more pleasant, soothing light in my apartment. Much better for the mood than LEDs. Does Aeropress still count?
I've considered more candles in the evening. How long before bedtime do you switch to candles? do you use them in multiple rooms? Obviously it wouldn't make sense to use a computer by candle light, but what activities are you able to do productively?
I try hard to get away from my laptop by 11pm. Then it's just Kindle without backlight/paper books or small chores like folding laundry.
