Hi Stephen,

Thanks Karin! I have found the duplicates and replaced then with original points. Glad you enjoyed the read.

Note that #5 includes the facts for 49 and 50, so you owe us 2 more facts. #14 is included in #25 - so you owe us a 3rd fact! From #25, if Nigeria consumes 40% of Guinness and Britain drinks more than Nigeria, then Britain consumes more than 40% of Guinness; that leaves less than 20% for the rest of the world - including Ireland. Ireland must not drink much Guinness. They must drink more Heineken, Carlsberg, or Budweiser. Well maybe the Irish are primarily drinking Jameson. Anyway, thanks for the facts. I enjoy your newsletter.

I will have to update those facts. I guess with 60 you can easily overlook one or two. Will update it shortly glad you enjoy the newsletter! Thanks


Friday 8th of May 2020

I guess I read too fast, and stand corrected. You did not say that Nigeria consumed 40% of Guinness, but that Africa does; therefore, Britain and the rest of the world consume 60% of it. Oh, well, I drink a lot of it in Texas.
