and travelled the world. Being a young musician and a
college student was hard work.

2. Future cars will not need human drivers. Imagine
giving orders to empty drivers' seats.

3. Some establishments, such as McDonalds and
Starbucks, offer free wi-fi to attract larger crowds. Are
fast food restaurants encouraging obesity?
