We found that free bus travel significantly increased public transportation use but, in addition, it led to improvements in cognitive function – particularly, improved memory.

It increased participation in volunteering activities and contact with older people’s adult children and friends. These findings show how a simple policy has had unintended positive consequences. It led to significant improvements in older people’s cognitive function and mental health – potentially by influencing social well-being.
