I don't feel "old". I don't "feel" elderly. But according to everything I read and hear, at 75, I am definitely 'elderly'.

Sometimes, contrary to my actual wishes, I do 'act' elderly. I can't walk very far now. And climbing steps is problematic.   But my 'mind' doesn't feel elderly. I'm still able to do creative things. In fact, I think that's what keeps me feeling 'young'. 

However, I admit I prefer 'golden oldies' in music. I never bother listening to 'modern' music. And I think a lot of the 'new' customs are silly. I don't understand the big deal about avocado toast. Or having 'gender reveals' when someone is pregnant.  We didn't know if we were having a boy or a girl--and it didn't matter, as long as it was a healthy child. That's what's important. 

On the other hand, I'm very much 'modern' in my beliefs. I think every person deserves the right to be happy, to love whoever they want, and to be whoever/whatever they want.  Who someone else loves doesn't bother me; it isn't my business.  I may not like how they look; but again, it's not my business. I believe in 'live and let live'.

My thought is: worry about yourself, not what someone else does.  I think the world would be a better place if everyone believed that. Let's hope that's what the future brings.
