When I read this article, at first, I thought it was impossible for senior people to do Tango because I imagined that the dance was very active and hard. However, I was surprised at the picture in which senior people were dancing with smiles. Moreover they paired with young men in foreign countries to dance. The remarkable points are that the dance is fresh for them, and that they dance with young men. As we get old, we aren't going to have oppotunities to do new things, so doing it is very stimulative and may stop their second childhood. And they don't have oppotunities to communicate with young men, so it must be happy thing for senior women to talk and dance with young men.
In Japan, the number of senior people has been increasing, so the activities like this should be done more. I think we should do fresh things with them, because stimulus is important to keep our life good.
