I really don't like clickbait titles like this. Is yours startup's killer feature your age? Why not describe what your service does in the title?
A lot of startups have founder backstories weaved into their pitch. 'Who are you, and why are you doing this?' can be an interesting story to tell.
And nice to see that apparently I'll be able to work into my eighties, no problems
There is a case that this is actually more impressive than for a young person to be able to do this.
it is definitely inspirational for me.
