Yes but there are too many factors that determine this...People can change because of the influence of others, it can be bad (f.e.gangs at school) or good (f.e.love), it can be religion, or the loss of someone or something (f.e.job), or any other grave calamity...etc. But I have never seen someone changing just on a whim for the sake of change...And for example people can change their lifestyles but that doesn't always mean they change their personalities. I mean let's say that a fat person starts training, or someone gives up on smoking...There are circumstances that necessarily change people's lives: a student's life is different from a worker's, or a single person's life will be different when she/he will get married and have children...etc.Changing one's mind about something or change of one's goals doesn't mean either a change in personality...So for a radical change in mentality it needs an impact from the outside. If someone starts to hate something or someone for a reason, does that count as a change? Sometimes yes, sometimes not...If it's a slow process, it's unnoticed.So a person normally continuously learns new things, meets new people, experiences new things that have an influence on him/her, and in the long run (f.e.5-10-15-20 yrs) of course it will seem as if the person was different from his/her previous self, but I wouldn't call that a change, but a development/improvement (in a good case, and in a bad case it's a moral decline/decay). :shrug:
