Lol the average British soldiers height was 5ft 8 inches in WW2, and about 5ft 7 inches in WW1.
Obviously the nutritional deficits of 1910s and 1940s British men were far worse than 2020s Japanese men. Stop trying to make this debatable.
I really not sure what you are trying to say or proof. Are you saying I'm wrong and therefore I should not be debating this?
I quoted that height figures from memory, when I was studying social and economic history when I was at university, over 30 years ago. where as you got that information from the first page of wiki!

Never mind, here's a direct quote for you. Happy now? I have no axe to grind, but you seem to have an issue of some sort.
