I'm 39 and right there with you, although I can't seem to get under 80 seconds for a solve yet. I've been cubing for a couple of months and have got the 2 look pll and oll down nearly now, just a couple of algorithms I'm struggling to remember. Love doing the last layer though, it's like magic.
I'm at a point now where I'm solving faster than I was (it was around the 3 minute mark a couple of weeks ago but I've just got a RS3M) and it is starting to feel "easy" now.
I also have one in my pocket most of the time, it's another hobby my wife hates lol "Do you HAVE to bring that thing with you?" YES I DO
