Whole blood donors, please take this survey? I'm doing a math project and need to survey several people. I couldn't get a hold of enough people and found this website thinking it's perfect, so please take a minute to help me out? Any help is appreciated! If you do donate WHOLE blood (whole blood only for this experiment please because I have to keep certain variables under control) : 1. How many times on average do you donate whole blood per year? 2. How many years have you been donating blood? 3. How many hours do you spend at school (high school, college... etc...) and/or how many hours do you spend at your work PER WEEK? Thank you!

Thanks for your help guys! I just need a few more data points if you have any friends that you can send here.
