I have a “Techina” in my Machzorim that says something about being able to light candles etc. till 100 years (it’s in Yiddish). When I catch myself saying it I quickly correct it to 120, although lately I’ve been tempted to add more years… Now that’s something I consider a klallah. But basically most of us are in denial about our mortality.
And to find The Bear is Back posting on this – 120 years – thread is also a serious wake up call, unless I’m confusing posters.
