Aged conversation

Today, I treated myself to some soup at a cafe that I really like. Because I was alone, naturally I eavesdropped.  At the table next to me, an elderly lady of somewhere between 75-80 was having lunch with a friend. She was rather spry for her age- I always used to imagine pushing 80 and being all wrinkly wearing a diaper or something. My mom is going to be 70 this year and she seems so young. I remember as a kid I thought 32 was old old old. That was how old I was going to be in the year 2000. I can't even remember what I thought the world would be like.
Anyway, I was eavesdropping on the lady and was enjoying very much listening to how much she hates getting friended on Facebook and why do people recommend things to you? Especially those who you didn't even want to be friends with. She bitched for a while about it and all the while I am thinking "damn, granny is so in the now"- watch she probably designs web pages in her spare time. Or apps.
Next she goes on to tell her friend about Weigh Watchers and describes the point system etc. It dawns on me that I could be eavesdropping on a conversation I might have with  a friend.
When do we actually "get old?" or is it we just get outdated and our bodies basically deteriorate?
Lately age has started to take on a different look to me. I detest the physical aging- since Christmas I have been given the gift of abundant grey/white hair growing all around my hairline and I am kinda freaked out about it. Sure, I have had lots of non dishwater blonde/ mousey brown hair growing but wham, so much all of a sudden. And the wrinkles. My forehead is starting to look like a topographical map. I can get all arty about it and say it's a map of the landscape of my life. Where is my barf bag? Aging seems so much more external- people seem to stay pretty much the same underneath it all.

Apparently our conversations don't change that much. We probably just get wiser until the senility sets in and then we just forget what the hell were were talking about anyway because how important IS it to go on about Facebook and Weight Watchers anyway? Whether we are young or old it seems we talk about the same stuff.  Things probably just take on different meaning as we get older. Granny probably didn't like the recommendations because she knows what she likes and doesn't need anyone telling her. Except that sounds strangely like Lulu. But at 75 or 80 (or maybe she was 65 but never wore sunscreen?) maybe we have gotten set in our ways.
Regardless the reasons, it all made me laugh.
