Is senility setting in?

Short term memory has never been a strong feature for me, and I’ve always been on the somewhat clumsy side of the physical spectrum. I’ve also developed a neuropathy in my left hand that has added to my clumsiness.

My wife worries that these are symptoms of senility. She thinks these issues are becoming more intense. I think she’s noticing them more since we’re both home 24/7 due to Covid.

Is there an objective way to tell if her worries are valid?
