Depends on wether you have kids at home, and also wether you are going out once in a while or several times a week. Also what do you mean having fun? Out to dinner and a movie? Or getting trashed and driving???
As a 33 year old, there are some things that some would call fun that you shouldn't be doing. Hanging out a a video arcade....fun but a man your age will draw looks if you aren't with a kid. (same thing at a Chucky Cheese)
Going to a college Kegger...fun but also probably not where a man your age should be anymore.
"Meat Market" dance clubs...fun and you could still pull this off, but at a certain age you start becoming sad.
This is the age you need to be showing some progress in your career, buying a bed frame, keeping your guitar in a case, and flossing everyday. We are full blown adults now, so we can still go have fun...but not windup in jail or on a website that parent's check when they are buying a house in a new neighborhood.
It is fine to have fun but please remember at thirty our definition of fun has matured. Most if all remember if a female act and carry yourself as a lady and male should be a responsible passionate man who loves to do right. Fun is relative, just be good and true to you
As long as you are cool with it, it is not wrong to go out when you are 30 years old. What matters is what you do and how you behave when you are out parting. Avoid doing things that you will later regret or things that are questionable.
What's wrong with having fun? As long as you don't neglect your responsibilities. Go have some fun for me too. :) I have lil ones at home that still need me at night. but when they don't, I'm a dancing queen, wahoo!!!
