       There are 365 days in a year. We sleep 8 hours a day, so we have 122 days for sleeping. Then our

work time has 243 days left. But there are 52 weekends in a year. Each weekend is two days. We lose

another 104 days a year for work. It takes us about one hour to have breakfast and supper. This comes

to 15 days over a year. But we can't work all that time-we need a holiday. Let's say we have three weeks' holiday. We don't work all day. Four free hours each evening takes up 61 days. We have to remember

that we get 2 days' holiday at Easter, 3 at Christmas and 1 at the New Year. There are also 4 Bank

holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours' lunch every day, and half an hour's coffee break. That comes to 30 days a year. This means that we have

only a few days left for work every year!
