DEAR DOCTOR K: As I get older, I've noticed that I have more trouble remembering certain types of information. But other types of memory are as strong as ever. Is this true, or just wishful thinking on my part?
DEAR READER: You've made an interesting observation -- and an accurate one. As we age, some information does become harder to recall, and new memories may be harder to lay down in the brain. But other memories remain as accessible as ever.
