A:Hello!Nice day,isn't it?
B:Yes.But it isn't as nice to me.
A:What's up?
B:I fail to sleep for quite a long time and feel uncomfortable these days.
A:How can that be?
B:I don't know.Maybe I’m old.Though I don’t want to admit,actually,not be young any more!
A:I have no idea about that.Does old mean unhealthy?
B:Not really.But,generally speaking,it does.Young people are healthier and more vigorous than the old.
A:Is that why I’m always more energetic than my grandpa?
B:Yes.And I’m almost as old as your grandpa.While youth means all that,old means nothing,nothing good exactly.Want to be young again!How nice the memory is!
