So on the main page, there was a story about cognitive decline starting as early as 45. As a 44-year-old, I can testify personally that it starts much sooner than that, though it's in baby steps.
There's nothing I can't do now that I couldn't do when I was 20, but it's somehow different. Learning new things requires a little more effort on my part, and it takes a little more time. Nothing too onerous, but it's certainly a change. I'm still a sponge for new knowledge and skills, but where I used to be a dry sponge, I'm a fairly damp sponge.
What about you?
ps - It took me 10 minutes to find how to write in my journal. Is that due to cognitive decline, or the stupid interface that puts the "Write in Journal" only at the bottom of my list of journals, completely breaking the temporal organization of the page? Presumably, any journal I wish to write now will be more recent than any journals I've already posted, at least until I perfect that time-traveling web browser I've been working on (homepage set to powerball.com, natch).
