With increasing age, the old men’s memory is getting worse. They always forget to take medicine, go to hospital to examine and so on. Crutches are old men’s necessities of life, which they would take with them wherever they go. It’s convenient for offspring to write memos for the elders, meanwhile the elders could write memos for themselves at anytime and at anywhere. Moreover, old men usually stay alone at home, their sons and daughters are rarely alongside. When they feel lonely, they may play the recordings which have been recorded in the crutch by their offspring.
