Not the age is my problem, but hearing loss and the need for adapters. I can't wear them 24/7 and when not wearing, I notice a dumpiness in my brain. Over the years I notice that it become difficult to follow by hearing, I need something to read and little more time to think about and to understand the topic. But it's just my perception. May be it's the age and dumpiness of hearing is just a coincidence. Can't sort it out. But, accumulated experience is even more worth than sharp thinking. Experience accumulation is a kind of byproduct of sharp thinking, that has been used by my younger me once in a while.
