positive word of warning, though: you might find that once you start eating more of the healthy stuff, your body will no longer like it when you eat … - Bear Grylls

Samuel Smiles ends his book with the following moving story of the “gentleman” general:

The gentleman is characterized by his sacrifice of self, and preference of others, in the little daily occurrences of life…we may cite the anecdote of the gallant Sir Ralph Abercromby, of whom it is related, that, when mortally wounded in the battle of Aboukir, and, to ease his pain, a soldier’s blanket was placed under his head, from which he experienced considerable relief.
He asked what it was.
“It’s only a soldier’s blanket,” was the reply.
“Whose blanket is it?” said he, half lifting himself up.
“Only one of the men’s.”
“I wish to know the name of the man whose blanket this is.”
“It is Duncan Roy’s, of the 42nd, Sir Ralph.”
“Then see that Duncan Roy gets his blanket this very night.”

Even to ease his dying agony the general would not deprive the private soldier of his blanket for one night.
As Samuel wrote: “True courage and gentleness go hand in hand.”
It was in this family, belief system, and heritage that Walter, my great-grandfather, grew up and dared to dream.

I look back now and can see how much my father also found his own freedom in the adventures we did together, whether it was galloping along a beach in the Isle of Wight with me behind him, or climbing on the steep hills and cliffs around the island’s coast.
It was at times like these that I found a real intimacy with him.
It was also where I learned to recognize that tightening sensation, deep in the pit of my stomach, as being a great thing to follow in life. Some call it fear.
I remember the joy of climbing with him in the wintertime. It was always an adventure and often turned into much more than just a climb. Dad would determine that not only did we have to climb a sheer hundred-and-fifty-foot chalk cliff, but also that German paratroopers held the high ground. We therefore had to climb the cliff silently and unseen, and then grenade the German fire position once at the summit.
In reality this meant lobbing clumps of manure toward a deserted bench on the cliff tops. Brilliant.
What a great way to spend a wet and windy winter’s day when you are age eight (or twenty-eight, for that matter).
I loved returning from the cliff climbs totally caked in mud, out of breath, having scared ourselves a little. I learned to love that feeling of the wind and rain blowing hard on my face. It made me feel like a man, when in reality I was a little boy.
We also used to talk about Mount Everest, as we walked across the fields toward the cliffs. I loved to pretend that some of our climbs were on the summit face of Everest itself.
We would move together cautiously across the white chalk faces, imagining they were really ice. I had this utter confidence that I could climb Everest if he were beside me.
I had no idea what Everest would really involve but I loved the dream together.
These were powerful, magical times. Bonding. Intimate. Fun. And I miss them a lot even today. How good it would feel to get the chance to do that with him just once more.
I think that is why I find it often
