I could drink a litre of water in about 30 seconds. Holding on to it for 90 minutes or 150 minutes if adding up the total time would definitely be a challenge.
When I went for an MOT I was asked the “do you drink a lot?” question, “yes” because I do a physical job in a warm environment, “do you pee a lot?” “Yes, because I drink a lot”, “are you tired a lot?”, “yes, because I do a physical job in a warm environment, on 12 hour shifts”
“Ooh, you might have diabetes!” More tests……. “No, you’re fine”. “Ooh, you might have high cholesterol, you’re quite heavy” More tests……… “No, your very much on the healthy side”. “Ooh, you’re carrying a bit of extra weight” Weigh me……… yes you are at the top of the chart………. Yes, that’s because I’m 6’4″, 4″ over the top of your chart for height so your BMI chart is useless.
