     Lisa, a 25year old from Beijing, recently places a number of very unpleasant statements on the

Internet regarding the elderly.They include things like "don't  rely on others", "don't expect others to

help", "don't be talkative", and "dont't be so stubborn". The underlying message was that elderly

people should not take advantage of their old age to demand special favours from others, particularly

from the young.This of course flies_in_the_face_of the Chinese tradition of respecting the elderly.But,

in my opinion, Lisa's "requests" might not be totally unreasonable.Old people do sometimes behave

like they're "stubborn"and "talkative". Still, the young woman is rudely insensitive to why the elderly

behave that way.As people get old, they become increasingly weakened physically.So it's natural for

them to ask for more help from others.As their memories decline, they tend to be talkative because

they easily forget what has just been said.The American psychologists D. R.Atkinson and G. Hackett

said that the brain is characterized by flexibility.It has the ability (most pronounced up to the age of 12)

to change itself as a result of experience.But, as the brain ages, this flexibility decreases.As a result, the

elderly are often inflexible in their ways.

     Therefore, old people need real care and deserve to be taken care of.Many have devoted most of

their lives to the wellbeing of the family or social.Their aging is no reason for showing prejudice (偏见)to

them.  According to Chinese tradition, older people are to be respected.As are Westerners.

     I live in the US for eight years, and in Hong Kong for 13.Never have I seen or heard anyone who

would openly tell old people "to behave themselves".

    We may encourage old people to be more selfreliant.But rudely demanding that they do so is ageism.

That's where the difference lies.
