Actually, in February I spent 22 hours on my mountain bike - I know you don't care snd perhaps not a big deal but it's a recent achievement in quite proud of.

Regardless, my comments are not about fitness. Young single people tend to have less commitments.

My partner and I have newborn twins. The only transport options are pram and car. We do have a bike trailer for them but it's not really safe until they're 1.

The same situation applies if you're caring for an elderly parent. Which I am.

The way you assume it's about fitness is kind of a "case in point" to be honest - you're incapable of considering that others have different transport needs.
