Ahem...Hambini?

he is mid 30s?

With +25 years experience?

Mid 30s is just a lower bound based on when he was an undergraduate. There's no reason why he might not have left school at 16 and done 10 years of shop floor engineering jobs before going to university, I suppose you could call that "25 years experience"

Maybe I need to start bigging myself up more, I have well over 40 years experience of "bearings engineering practice" as long as you count being able to strip, reassemble and adjust a loose ball bottom bracket when I was knee high to a grasshopper 🦗 🙂
