Study: multi-tasking does not improve with age

SAN FRANCISCO

Researchers at UC San Francisco used brain scans to discover that people over the age of 60 have a tougher time remembering to finish one task while being distracted by another.

Doctors say as we age it's more difficult for our brains to quickly switch between networks of nerves assigned to each task. The topic has growing importance as people stay in the workforce longer.

The study is in the "Proceedings of the National Academy of Sciences."
