– when all your old jeans refuse to fit. The ones that used to fit perfectly.
– when you get on the treadmill and are panting within minutes.
– when you realize that all the old stretches that you used to do easily,now, are a huge effort.
And worst of all, its summer and you bulge out in all the wrong places in summer clothes. And probably the only time, I’ve been thankful for British weather, which allows you jackets to hide tyres around your waist:)
