Older individuals, of which I am one, know our limitations. Statistically, we are closer to death though accidents and a wide spectrum of disease affect all age groups. In that respect, we old people have been lucky.
Older persons possess the benefits of experience and perspective. In general, we know when to seek assistance and are more than willing to do so. Though the term wisdom is perhaps an exaggeration, a long life does impart knowledge that is accessible only in books or on video to those in younger generations. Having lived through multiple decades, political upheavals, cultural shifts and social movements, old people assess and approach current problems in the light of our personal history.
Unless older individuals are demented and even if we are physically infirm, we have a lot to offer. More than giving advice and telling our stories, we can provide leadership, especially when surrounded by capable lieutenants and assistants. Agism is just another form of discrimination; like the others, it is based on ignorance.
