And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly

With the percentage of people over age 65 expected to nearly double by 2050, it's important to weigh the health benefits of screening against the risks and costs of routine testing.

In many cases, screening can lead to surgeries to remove cancer, while the cancers themselves may be slow-growing and may not pose serious health problems in patients' remaining years

For better or worse, batteries make possible our mobile-first lifestyles, our screen culture, our increasingly globalized world.

However, higher doses of screen time were clearly associated with lower happiness.

However, the "screen time" hypothesis, advanced by researchers such as Jean Twenge, is that electronic devices and excessive time spent online may have reversed these trends in recent years, causing problems for young people's psychological health.

In fact, when Twenge previously used this data to suggest a screen time effect, some commentators were quick to raise this problem.

Next, Twenge's team dug a little deeper into the data on screen time.
