It's not that simple.

The last couple years, a buddy of mine did exactly what you proposed: He had massive GI problems, so he started watching what he ate, and… his problems became much worse.

Fast forward to a couple months ago, when he sees a doctor specializing in this stuff and she tells him to significantly reduce plant-based food for a while "because your gut biome isn't able to handle it right now. You should go eat a burger every now and then." So he's been following her advice and all of sudden he is without any GI issues whatsoever.

My buddy got lucky (found the right doctor, could eat his way out of it) but if your gut biome is seriously out of whack, I can definitely see the appeal of an FMT to kickstart your recovery.

> Improving GI problems would be expected to improve mood.

While improving GI problems might improve your mood, I don't think it is accurate to equate depression with "bad mood".

A friend of mine has IBS and while her GI problems are under control most of the time, she still gets hit hard by depressive episodes.

The Linux kernel is another great example. Random commit from yesterday:

I was kinda expecting to see the name "chardet" pop up here. :-)

> And LBO debt isn’t “pushed” onto the company’s books, it’s never on the sponsor’s (LBO shop’s) books in the first place to any material extent.

Doesn't the LBO shop still need to pay off the debt, technically speaking? AFAIU the company's assets (hospital in OP's example) are used as collateral in a credit agreement between the LBO shop (as the hospital's new shareholder) and the bank. But unless I'm mistaken, this is not exactly the same as the debt being on the hospital's books and the hospital having a credit agreement with the bank. (For an increase in debt on the liabilities side of the balance sheet there would have to be an equal increase of assets on the other side. The hospital didn't receive the cash, though, nor does the hospital suddenly own itself.)
