I used to donate plasma. I was able to bring in about $200 a month from BioLife. And the cute techs thought I was still in college 
I actually got banned from one facility for writing a poem to one on the assistants. She was cute but I didn't give it to her, I posted it on the cork board.
Let me think .... yeah it wen like this;
To gently stroke your golden hair,
Between our bodies only air,
To lay you down with kisses full,
To feel our souls magnetic pull,
This thought for me so very cool,
To gently plant my yearning tool,
That should I die while having fun,
I would not go until you cum!
The admins were not amused.
