On Monday night, I had a very long telephone coversation with an old uni friend. We rarely get chance to talk so much now, and despite the fact she wasn’t physically present, it took me back to the days when we lived together – both at university and afterwards in another city. Back then, we used to have lots of conversations. One that has always stuck in my mind was of all things about stretching. It was almost twelve years ago when we were freshers. Coming out of an aerobics class, she said “Doesn’t it feel amazing when you’re stretching after exercise?”. My brain comprehended what she’d said, but it was only this evening, when cooling down after my second zumba class of the week, that I understood. Somewhat belatedly, I can finally reply that yes, Sarah, it feels amazing.
