When a person turns 40 what physical, psyschological or emotional changes a person goes through?

Answer 1

I'm not too sure what you're getting at - there is nothing particular about one's 40th birthday! As we age, things change for us in the physical, psychological and emotional spheres, but it's gradual and continual. The physical changes of ageing seem to hit people more in their 50s, but for some people it'll be earlier and others later. The physical changes are most commonly stiffness and pain in joints, perhaps less energy. For women, there will be menopause which, despite the myths, doesn't have much impact on quite a few women, while affecting others more severely and a few very badly.

Psychologically and emotionally, the "mid-life" phase (sometimes termed 'crisis') is most well-known and most mis-represented. At some point, when we have done all that work of establishing who we are, settling into a relationship or a pattern of serial monogamy or whatever, for many people having children, working and either trying to get better jobs and work our way up or resigning ourselves to what there is for us - when all this is done, we come to a point of wondering what on earth it's all about - why have we done this? Who are we really? It comes to all of us at some point between about 30 and 60, and may be a fleeting anxiety or a major shift in our sense of our selves.

It would be easier to give you an answer if we knew why you were asking.... as that would clarify what the question really is.

It is not on a particular birthday that you go through changes, it is gradual and finally you realize that you can't do things how you did before. You find you can't keep the same hours, it takes more effort to keep in shape, your skin isn't as tight, you get gray in your hair. The emotional part has to do with accepting all the changes you are going through. Some people have a harder time than others.
