I think that independently that we are talking about personal experiences on both sides, the only scientific proved is that aging biologically takes changes, different hormonal levels, decrease in some skills for different people in a different level. There are people who are older than me whose physical skills are much better than mine, because they train.
So, I still think we have prejudices and lots of myths about elderly people.
I’m aging and what I see is a loss physical abilities but my mind is better than ever. So, I think we are being fairly unfair.
Thus, in my opinion, we should be thankful for the help they offer us with our children. And with the patience they are doing it. They took care of us and now of our kids.
We should recognise their labour.
The only way the person changes is by the circumstances, they have more experience or this time, unluckily, if they develop an illness that can affect their brains.
