I don't think this applies to me, but I think that the idea of it is good. We should always be challenging ourselves to try new things no matter what our age. Learning a language is something some people do. I have been learning French for the past 18 months. Maybe I will get to use it, as we are travelling to Canada soon. Travel is one way my husband and I have been enriching our lives, by learning about others. Hopefully the latter part of our lives will be spent doing plenty of that. I have joined another group, that I have been wanting to join for a while. We try to challenge ourselves by going out to interesting places, and not sit home all the time doing nothing. We learn lots from doing so, and become stronger as a couple. I don't think mid-life crisis is the appropriate phrase for me, but for some it may be. When my husband retires he will take up some new hobbies, and he has thought of some he would like to try. He will probably come to some of my clubs too. It is good to challenge yourself, as we evolve and change and learn in the process.
