Perspective IS everything.
My grandma........seriously? I never thought of her as being old. Not once. Her friends were "old", every one of them, but not her. She was ageless. It really stunned me that she died at 72. But I didn't think of that as being old, even though I was 16 at the time. It was weird because I knew friends ect of hers that acted / dress / attitude of old at like 60. But she remained ageless to me.
My "Dad" (not bio, step dad who raised me) was 21 yrs older than my mom. He was in his 50's when they met......I was 2. He also was ageless. He never ever acted "old". He was one of the most active people I've ever known, aside from grandma. He had a heart attack (his 3rd I believe) coming back in one morning after working his acre garden plot.......he was 72 or 73 at the time, maybe a bit older.
husband at 40 acted older than both my grandma and dad did when they passed. This was pretty hard on me as I just couldn't adjust to it. And so I gave him flack about it, alot. lol By 60 husband was acting like he was ancient. Drove me nuts. I was like, seriously?, your mom is in her mid 90's and acts younger than YOU! ugh
But..........I know folks in town my age that act like their "old" too. Me? Not so much. I don't feel "old". Heck, I don't feel any different than I did at 18. (my body, however, doesn't always agree with this)
