Imagine it's 8pm and you try to work 9-5. You get an email or slack message, you just quickly glance at it and it sounds like there's a tiny fire somewhere in the system that you know how to fix/respond to. It's very easy to sit down on the computer since it's literally a few feet away and get sucked into an 30-90min debacle multiple times per week. I use the same computer for games/internet time and work so that definitely doesn't help. I just don't have room to set up another desktop since my home office has a nice desk, monitor, chair already.
