Input:  Person1:     So the company decided to cancel your trip to Hong Kong ? 
 Person2:  Yes , The SARS epidemic is not under effective control yet . So I'd better not risk it . 
 Person1:      Maybe it's a good things . If you don't have to go to Hong Kong , you can take a break and take things easy for a while . 
 Person2:  You are right . Maybe we should work out a fitness plan and start to do more exercise . Sitting around in the office all day is no way of keeping fit . 
 Person1:      That's a good idea . Let's see if we can get more people in this plan . There isn't much business these days anyway , so I think many people will be interested .
