This is The Guardian.
Today is the Jim Genzies pub.
We are outside the Albert pub in Victoria.
Let's go and see who's in there.
This one's quite busy.
It's 6.30pm in central London and I'm in a busy pub in Westminster.
All of the seats are taken, the empty glasses are piling up and conversation is just bordering on shouting level.
We're journalists from The Guardian.
We're making a podcast about Genzies.
Post-work drinks used to be standard operating procedure for young people in Britain.
When I first moved to London 20 years ago, it's what I did many and sometimes every night of the week.
But now I'm looking around and I'm thinking how can I be one of the youngest people here?
I approach a group of men pints in hand.
Do you mind me asking how old you are? 61.
I'm definitely not Genzie.
You can have a laugh in the pub, can't you?
You like your hair down.
So if young people aren't in the pub, where are they?
I find the answer in a busy basement around the corner.
Eleven and a half million people in the UK now have a gym membership and all-time high.
