Can someone get asthma over time?

Yes: While most asthma tends to develop in young children, asthma can develop at any age. In adults, new onset asthma may follow a severe respiratory infection or allergen exposure at the work place. Sometimes, asthma can occur in childhood, resolve (remission), then re-occur again in adulthood. If symptoms are suggestive of asthma, no matter the age, the person should be evaluated.
