That's an interesting subject to me, because i found myself constantly working with different age groups (i was 21 when i was working in a company where everyone was ~10 years older than me, now that i 'm 31 i 'm doing some postgraduate work where i get to be with ~25 year olds). I was always considered "too serious" for my age group as a kid (and frankly i still find my age group annoying). My permanent age must be 35. Would be interesting to see what's yours.
