I have to admit that I didn't really experience any noticeable cognitive deficits post-op. However, like you, I'm 'attached' to my computer and between posting (often lengthy) messages here and on other websites I visit regularly, it keeps my mind pretty active. I was posting here the day I arrived home from the hospital, a brief 5 days after my surgery, and I've never looked back. I also read a lot, mostly non-fiction, including newspapers. Immediately post-op, I did a lot of walking at a local park, usually two miles a day, to help me regain my balance. My wife accompanied me and because it was summer, we had an enjoyable time. As winter set in, we abandoned our walks and, unfortunately, we didn't resume them the next year. I found that simply doing the things I used to do required a bit more effort, mental and physical, and that served to keep my mind 'sharp'.
