My donor agency limited the age of donors to under 30, but that does not mean all agencies do. And you will have a better chance of being selected if you are a recognizable 'type' (i.e.; Asian, Swedish, Native American, African, Irish, etc.) and are pretty, and if you are a little taller than average. It's like a cross between a dating agency and a medical clinic. lol The money is good but it's a lot to do, with the shots and the meds and the medical appointments.
