Physical circumstances like the bodily aches and pains and some changes in looks is the only difference.
In my mind and ways of thinking about life stay the same.
I don't have any trouble remembering my biological age.
Not yet anyway.
Susan do you mean like you just always feel a certain age?
I feel like 23-28 maybe and that has never really changed as I grow older.
I have no idea why and its not really a problem except it makes it even harder to fit in with people my age.
I just feel mentally young (not necessarily immature) and that seems to have me liking things that people younger than me like. Its not easy to explain I guess.
