I'm in my late 40s. Definitely I'm not the same person, cognitively, that I was in my 20s. It's not all bad, though. I'm sure I would score lower in an IQ test, but I'm actually more capable than I was back then. Experience counts for a lot. I can deal with emotional stress much better, or perhaps I can avoid the situations which cause it (more likely). I can see other people's point of view a lot easier now. I can see gradations in judgement, where before everything was black and white. It sucks to lose the horse power, but I more than make up for it by driving the car in the right direction. I suspect the decline will continue, but in many ways I look forward to what I will be able to accomplish when I'm older.
