Now,'some years on',with some health issues,that best thing to carry but had no weight,was youth,a fit body and the confidence and bright outlook that came with it,gratis. You don't get that again! Decent muscles,a clear sky,a walking companion,an early day...you don't get better.
There's been some times and on some walks where I have said 'it can be no better than this',and sometimes(confession)I can be a tad on the negative. The Mary Berry ingredients for such are that sunshine,a good view,a body still able,and your goal/bed/evening meal just those last few miles away.
Heaven meets earth.
