Yep all the time. Listening to pop master on radio 2 I'm always at least 10 years out with music. The vet came recently to x ray one of my horses feet and asked when the last time he had them done. I said last year (2017) She checked then said no, it was 2016
Absolutely! Someone once explained it mathematically to me (very boring) and it's to do with ratios. Eg If you are 10 yrs old 1/10th of your life is 1 year - if you are 70 it is 7yrs..... or something on those lines. Jim could probably explain it better. :)
