What no one has yet discussed is being a plasma donor to keep the bad proteins down that have accumulated over time. You can donate 1 pint plasma up to twice a week, they replace it with saline and return the red cells to you. If someone went weekly, say, they would sooner or later have removed all the old plasma by dilution with the new plasma that replaces it - I dont have any data on how many donations it would take to remove 95% of the old plasma. No albumin is needed since you are only removing 1 unit and the body can replace it quickly, not like removing half the blood volume at once. Plus, they pay you to donate. - Jay Caplan
