It's very "My name is Prince Andrew and I cannot sweat"
RFK's "brainworm" was just an excuse to pay less alimony to his ex-wife, because he claimed that it reduced the income he could make.
The only proof of the worm is RFK saying that it existed, but he claims that his brain fixed itself two years later, and he's all better.His ex-wife he died by way of suicide by then, so he no longer needed to claim that he had reduced capacity in order to pay her less.
If you read the book "Robert F. Kennedy, Jr. and the Dark Side of the Dream" it outlines how he was cheating on his ex-wife, sexually assaulting the babysitter, and would often tell his ex-wife that she should kill herself.
It would be better if he did actually have a brainworm, but it's more likely that he's just the kind of monster that would become part of Trump's circle.
Even if you eat meat, a multivitamin a day is a good idea.
As for the thing that people always bring up, protein, the lazy way is to make air-fried tofu to replace chicken in various dishes. If you airfry tofu, you don't really need to prepress/drain if before you cook it, just cut it into pieces and put it in the air frier for 8 minutes.
If you're anti-vitamin for some reason and you don't mind being a little trashy, B12 is what you are likely to be short on with a vegan diet. Look at the amount of B12 in an energy drink. If you drink a 1/4 of a can a day, you have your B12 covered. But seriously, just eat a multivitamin. Even if you eat meat, there's probably something that you're missing.
