why is the weekend so short?!!

WHY IS WEEKEND SO SHORT!! who ever invented the week? why is there only 2 days for weekend? that is not fair. we should have equal number of weekdays and week end... hmmm... like 3 days of weekdays and 3 days of weekend and alternate week of 1 day of weekend and weekday to make thing fair right? ok maybe that is a bit the trouble some... other wise we can employ a alternate week working scheme... like we work ofor one week then we rest for one week... cos seriously.. i really dun care if it is a weekday or a weekend.. as long as i dun need to go to work!! wahaha
