I would say, YES. My sister did the dirty work for us, and I didn't like what she found, so I steered clear and moved on with my life. Not to deter you, but be prepared. Remember, if you never expect anything out of life, you'll never be disappointed.
It could be a wonderful reunion, or a horrible meeting, but if you don't do it, you'll never know, and it will always nag you. Something about a biological parent defines who you are and where you came from, a gotta know kind of thing.
On the other hand, the majority of a person's personality is formed by age 5, so if you were adopted very young, your adoptive parents have a lot to do with who you are. They helped form your personality.
I think the most important thing to know about biological parents is medical history because so many medical issues are genetic.
Good question! Seems as though I could go on and on, but not, I'm done. Best wishes in your endeavors.
