The ancient Egyptian noblemen usually would be very busy with their daily appointments with overseers of their much treasured land. However, music played a vital role in their lives. To pass time, they threw lavish parties. Consumption of beer, wine, and narcotics was common.
They also spent their leisure time in their own gardens next to their houses like people do today. They could go outside and relax. They also loved to over-stuff themselves and enjoy a good laugh. Fishing was also done at their free time and would go severally to river Nile. Most of the fishing was enjoyed as a timeout from hard work. They also hunted for sport. Noblemen caught wild animals.

Fairtrade is paying producers a reasonable price for the goods that they produce. Many farmers in LICs are paid very low wages. This means that they cannot escape poverty. Fairtrade gives farmers a better chance in life.
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
Its spread mainly because of the pest rats and also fleas
