If you support segregated cycling infrastructure in Hackney

Yes, perhaps if youtake your own words within the context that you put them yourself.

However, you're not without point.

But what's the reason for that?
Do you travel from an area with a typically lower age demographic such as the hipster haven of Hackney?
Do you travel to an area with a typically lower working age demographic such as along the Hipster Spice Route?
Do you travel at a time more popular with the younger age demographic such as at Hipster O'Clock? (some things you just can't refuse)
Are you conflating being a cyclist with youthfulness? (i.e. have you actually asked cyclists their age to get a proper sample or are you possibly falling for that effect where active people appear younger than sedentary people?
Do you live in a society where we've had decades of the car being part of an increasingly aspirational function and younger people are part of a new wave of change in that, along with other developments such as social media, technology ownership, greater social liberation in freedom of self-determination in actions?
