What are you worried about? In my experience many jobs simply don't have 8 hours worth of work to do in a day, so there's downtime. (And the ones that do have 8 hours+ worth of actual work to do, without breaks, are the ones that pay near minimum wage and are a bit terrible). Since you're on hacker news I presume you're aware that it is nigh-impossible for a programmer to just program in flow state 8 hours a day every day 5-7 days a week. I usually get 4 hours of good work out of myself on bad days, 6-10 on great days or under deadline pressure, but can't keep that up many days in a row. Slack-ing off and the web help me decompress my brain in between uses.
