Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now… perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers?

While many flights by plane are controlled automatically by machines, most people today wouldn’t let their car drive itself. That’s because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won’t turn the car right or left. It won’t stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS（global positioning systems） that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at.

In addition to computers being ‘smarter’ than people regarding the best way to go or knowing how close another vehicle is, computers don’t get sick, tired, or angry. This means they won’t make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend’s personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle.

So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn’t have any jobs.

Dogs already guide blind and disabled people and now they are to be trained to help people with dementia．The idea developed by some university students will now be put into practice by Scotland Medical Center．The research is meaningful, for there are 670, 000 people in Britain who have dementia and by 2021 this is expected to rise to one million．

Dementia can make people confuse night and day or forget basic things such as washing or drinking enough water．The dogs would be trained to help to guide them through the day．

Joyce Gray from Scotland Medical Center said, "People in the early stages of dementia are still able to live a relatively normal life, and dogs help them to maintain routine．M For example, people with memory loss will tend to forget to take medicine, "but if a dog presents them with a bag with pills in it, there's a greater chance of them taking it．"

Ms．Gray also said dogs were perfectly suited to remind their owners to eat．"Dogs have an ability to say 'it's my feeding time^, so there would be a note in the cupboard next to the dog's food reminding the dog's owner to eat too．"

The dog would also encourage the owner to take them out for walks．"It gives a reason for the owner to go out into the community," Ms．Gray said, "We did a test with an elderly person walking down the high street on his own．Then we gave him a dog on a lead and he did the exact same walk．That time people would come up to him, chatting or smiling and making eye contact．We hope we'd see this with people with dementia too．"

There is one more advantage of using the pets as companions．Since conversation can be increasingly confusing for people with dementia, dogs can give them a sense of silent support and companionship．Ms．Gray said, "We have found that people may forget familiar faces but not pets．People light up when they see animals．There is a speechless bond between the dog and its owner．w
