File this under things that we already knew, but a confirmation by science doesn’t hurt. A scientific study by Marmite has revealed that Mondays do indeed suck.

The findings fo the study, as reported by The Telegraph, indicate that many people don’t smile on Mondays until 11:16 am, and that half of us won’t turn up to work on time, either. Mondays also tend to be fairly unproductive, with only about three and a half hours of actual work getting done. And those in the 45 to 54 year-old demographic will moan for about 12 minutes on Mondays, making them the most susceptible to the suck that is Monday.

Experts indicate that the reason behind our hatred of Mondays is a result of humans being “governed by deep-rooted tribal habits” and that we prefer to ease into the week rather than tackle it head-on first thing Monday morning. In fact, those that do the latter may end up burning themselves out before Friday hits.

Want to make Mondays suck less? Marmite also revealed the top five ways you can try to do that:

  1. Watching TV
  2. Sex
  3. On-line shopping
  4. Buying chocolate or make-up
  5. Planning a holiday

So when you start off the week with a little less enthusiasm than your employer or coworkers might like, just tell them that it’s a proven scientific fact that Mondays generally suck.
