Resume question anyone dropped old dates before , what needs to be there or not?

my problem is it makes me appear dated despite the fact most people who know me think i'm relatively young , being in my 30's some of the dates are starting to appear like there a long time ago. like to tell an employer i went to college or had a part time job in 2007 sounds like a very long time ago and i look younger so they might not even realise i was that old to begin with

i'm just not sure what i could drop without looking like i was trying to hide my past , although it may be necessary to do so at this point
