People in their 30's, what's your experience of London like?

London is feeling very different in my 30s compared to my 20s.

It seems like every person I know is overworked, stressed and feeling unappreciated at work. A majority of my friends are unhappy with their jobs and many are working around the clock because their employers won't fill vacancies.

I've noticed social plans are much more sporadic because no one has the physical or mental energy to do things anymore (even without kids).

Likewise, in almost every conversation I have with people my age, there seems to be a real concern about a lack of purpose.

Curious to hear if this experience is specific to me and my friends or a part of a larger trend for this age group.
