@seacreature we walk with poles which you push against the ground to give more impulsion and walk with straight arms and roll forward on your foot - it just means I actually raise my hear rate and don't dawdle along taking photos all the time. There's probably a video on YouTube.
@chrisiow I'm going to go back when I can spend time - sadly no cake - straight on to next appointment with no time to spare [sad bag of crisps only emoticon].
