So I saw part one of Pippa's old streams and apparently she is one of those people who can eat whatever she wants and not gain weight. It's been theorized that there is a link between the gut bacteria and weight, so it's possible she may be a viable donor, although I don't know if her diet or other habits might disqualify her.
Human Microbes can apparently pay up to about $180,000 a year too.
The idea of her selling her feces is both amusing and within the realm of possibility for her given her antics.
@thhrang if you're willing to do so, would you make sure Pippa see this? This has the potential to be entertaining. Ha!
