That’s how it always is. I have one coworker in her mid twenties and another in her mid forties (I’m in my mid thirties). The younger one was saying the older one looked good for her age and I was like “??? But she’s not old???” But just like I see 50 as the line for older and 80 as the line for elderly, she sees them as 40 and 70, respectively. I’m sure my 75 year old dad doesn’t feel five years away from elderly (unless his knees are acting up)
