how do you know you are getting old?

when i was young ppl used to guess my age yrs older.a rishtay wali lady said "larki 30 se kum ki nahi lagti" n my mom n sister wanted to smack her head.
now that i'm in 30's they guess me waaay younger. few months back 2 elderly ladies just got so curious of me they said i didn't even look married they can't believe i have pre teens. :@: now i guess i should wait for a proposal :D
