Drug discovery in Singapore

摘要

In rural Africa,relief workers had a problem.They dispensed AIDS drugs to illiterate villagers and couldn't be around to remind them to take one pill in the morning and one pill in the evening every day.So they painted a yellow sun on the bottle of morning pills,and a moon on the evening pills.When they returned six months later,a third of the pills remained.They asked why the villagers hadn't taken them all."Because some days,it rained," one said.
