How can one combat ageism mentally?

Many ageist behaviours may come from the false notion that older adults are disinterested in what goes on in the world. Prove everyone wrong by staying updated and mentally active. I think being independent can be a great solution. Some people believe that seniors need help with absolutely everything and are incapable of doing things independently, leading to forms of ageism. But if you do errands on your own, they’ll see that age is not holding you back.
If you see someone discriminating against you based on age-related factors, speak up and defend yourself. I’m not saying you need to make a big deal of any remark or possibly insult, but make sure no one dares to belittle your achievements or consider you inferior because of your age.
One more word: Stay positive. Keeping a positive attitude is hard, but it helps a lot with overcoming ageism. No matter what comes your way and how people treat you, never give up or succumb to the negativity around you!
