You respond to a tech post that has nothing to do with animals or the environment with nonsense about cholesterol, that also has nothing to do with either animals or the environment.  You really need those B12 supplements as brain damage is clearly starting to set in. And yes, I'm old, so will you be, just at a way younger age, in actual years,  than me, on your current "premature aging diet. 
And what's more, if you care for those two you wouldnt be vegan if you had researched the facts first as you would have realized mono cropping hurts both way more than cattle farming. And as for cholesterol, the 20th century called and it wants it's science back. Cholesterol doesn't make anyone sick or fat. Google David Diamond, Ivor Cummings, Michel de Lorgeril and Uffe Ravnskov and look into their work. The LDL hypothesis is pretty much dead, and guess what, it's those plant based sugars and refined grains and plans based high omega 6 ultra processed seed oils that cause CVD and cause obesity, not the eggs and bacon. 

Enough said, [here](https://steemit.com/nutrition/@mattockfs/some-thoughts-on-a-sustainable-and-healthy-diet) is a link to get you started on your obviously long path away from ignorance, premature aging and B12 deficiency induced brain damage. See you on the other side.
