We will all likely become victims of Ageism eventually, why don’t more people care?

Firstly, I think we don’t understand what it feels like to be a victim of ageism until we are.
Secondly, I think it’s because of the same reason we continue to smoke even though we know it’s unhealthy; we don’t believe it’s going to happen to us.
And the third reason I can think of is that ageism is a lot more complicated than other stereotypes like racism and sexism.
The complication is that everyone gets old if lucky enough. The problem is, it doesn’t just affect us after we reach a certain age. It is always in our heads. Some may feel “unqualified” because of their age in their adolescence and early twenties.
At the same time, we are scared of ageing; the first fine lines and grey hairs scare the hell out of us. Because deep down, we feel we are becoming “unfit.”
The best thing we can do is accept that we are constantly changing and believe it to be a blessing. After all, switching is a rule of nature; we were all nothing but a single cell at first.
