As a granddaughter of my lovely respectful-aged seniors, I can see the issues that they face: lack of communication, closed-minded, lagging behind the development in society (technology, policy, social-political topics, etc). My idea to solve these issues is by paint activity.
We would need to gather people of all ages in a place, give them tools that would be needed and the various topics. In that way, seniors will be heard, they will learn new things, they will understand other generations more and it would be pretty entertaining for all-aged people. Before painting, hosts will provide participants with information, could be verbal or visual, then everyone will paint how they feel or think about information that was given. When everyone is done, one by one will summarize what they painted and everyone else could interrupt to commentate on it if needed.
Also, everyone could share their experiences of that topic too and I think, that it could be a good way to connect and to include new perspectives and experiences in elderlies lives
