It's easy for me to lose track of time once I start reading articles or posts. I would have this mental checklist where I would have to catch up on the news, read about relationships, check out beauty and health care tips, say a couple of pithy things on a history or other forum and watch videos of cats or other baby animals. My job is stressful and requires a lot of mental energy so I find it's my way to wind down, but I know I spend way too much time at it.
