I guess I can now pass as part of the over 40 crowd since I am 40 ... I just started learning (electric)guitar this year really . I had an old acoustic in my hands about 30 years ago but I have more of a grasp of how to learn now than I did then . If I can understand why or how something works , I can make it work .Back then it was only "do this" like monkey see ,monkey do -took things at face value and never really questioned it further. Now its easier to know the breakdown and the construction of music,chords .I'm not saying I understand it fully...not in the least. You might just be trying to learn with a guitar that doesn't suit you or maybe it just needs a good "set up" .I found that once my axe's action was lowered , my aging fingers worked the frets much easier. Find a few simple songs and tab them out . You'll get it.
