Hi Ahtoh,
Technically, both of the are wrong!
I retired from my job at 35.
You would be very lucky! Retirement is isially done at a much older age, when you are least over 60! Usually when you "retire" you do not work anymore for the rest of your life.
I dropped my job at 35.
Usually you would say " I quit my job at 35". This means you leave one job but maybe plan to take another.
