That's not healthy. Please take some time off for a vacation and return to a normal 40 hour work week.

There's a good reason why people fought for a 40 hour work week. Life is not just about work; you need to relax too.

I refuse to work more than 32 hours a week, and that's working out very well for me. I have time for my hobbies, my kids, my friends and family, and I have time to just do nothing at all on occasion. And the hours I do work are very productive as a result. Admittedly my current project is so interesting that I often work a bit more than 32 hours, but it's because I want to, not because I have to.
