Older people who want to preserve their faculties may wish to consider rationing their TV time. A large new study of older adults found that those who spent at least 3.5 hours per day watching TV experienced a greater decline in verbal memory.
Researchers at University College London in the United Kingdom analyzed data from the English Longitudinal Study of Ageing (ELSA) on 3,662 adults aged 50 and older.
In 2008–2009, and again in 2014–2015, the ELSA participants had answered questions about the time they spent watching TV.
At these times, they also completed tests of verbal memory and fluency.
