For the average eater, the animal-friendly life of a vegan must have had a similar appeal to that of dry bread until recently: limited appeal.

Almost everyone now knows a few of them, at least vegetarians, and the old prejudices are melting away like warm butter.

Even more: Veganism is now blossoming across cultures into the noblest of all diets.

Even dog owners, for whom feeding raw meat is the only option for a species-appropriate diet for their four-legged friends, can now read in the magazine "Plos One" after evaluating 2536 four-legged friends' fates that the completely meat-free and dairy-free housemate ages healthier than their rumen-smacking conspecific.

The Intergovernmental Panel on Climate Change recently named plant-based nutrition as the gold standard for climate-friendly lifestyles, and as far as our own nature-friendly well-being is concerned, nutrition researchers from Bonn showed a few months ago that vegan food – apart from the higher water consumption – is now clearly superior to Mediterranean cuisine.

Of course, British ornithologists from the University of Bath have provided the final proof of vegan wisdom.

Weaver birds from Africa are her role model for exemplary veganism.

These African songbirds, famous worldwide for their intricately spherical web nests, come in two versions.

Some breed in colonies on savannah trees and feed almost exclusively on grains and seeds, others prefer the protection of the forests and constantly chase after the insects, which are only allowed to enjoy their carnal existence for the blink of an evolution.

58 years ago, British behavioral scientist John Crook had the glorious thought that these differences might not be accidental - that diet, habitat and social preferences might be related.

The ornithologists have now presented the statistical evidence for a good hundred of the 118 weaver bird species in the "American Naturalist".

Vegans are therefore, to put it in a nutshell, the more socially acceptable companions.

Which has consequences: The grain eaters not only breed together, they also swarm out together, and inspired by this sense of togetherness, this also gives them even more sexual partners.

And because the myth is still spreading that vegan food leads to ugly malnutrition, this should also be mentioned: Because the bridal market is so competitive in the flock of birds, the feathered costumes of the seed tasters also get a more extravagant look than those of the meat eaters.

So vegans are more beautiful, and their everyday life is one big celebration.

Veganism definitely does not make you lonely.
