(CBS)- A new study says commuters should consider leaving the car at home. Research in the British Medical Journal shows significant health benefits in walking to work, cycling, or taking public transportation. Commuters who chose those options, rather than driving were found to have healthier body weights and a lower percentage of fat.
(CBS)- Elderly people often struggle for a good night of sleep and a new study has found a possible explanation. Researchers say a group of neurons act as a sleep switch in the brain. Older people and Alzheimers patients start to lose those neurons, which damages the quality of their sleep. The study in the journal "Brain" shows that people in their seventies sleep about one hour less each night than people in their twenties.
