We need to focus on the message, not on the person who gives it. If we have adopted this attitude then even very young people, we can hear their good ideas and accept them. I feel that sometimes, from young people, their minds are not biased and they can see things in a different way. They are more natural and spontaneous. Older people have more biases and tend to have been more influenced by society and the brain side of their nature.
Young people are more innocent.
The basic quality of human nature, the basic innate goodness in each of us, is more intact. Older people tend to be less spontaneous, more biased. But, I don't know. At school, we have been studying the importance of the rain forest and preserving the environment. Now, this is a new problem, in part due to population, also, humans using natural resources too extensively.
