Good morning Dennis,
As you are one of my Biggles type heros, I look at this as a chance to offer some help, I am 14 years behind you , but apart from Knackered Knees and one shoulder creaking ( too much Cricket and Rugby when I was younger)I think I am fit, but I am told my BP was a little high, after explaining to the Quack my want of flying he suggested to cut out this, that and the other and see what happened, well it did have a result and the BP dropped down to what was considered a reasonable level ( I have never smoked, nor been a coffee drinker apparently that too has an upward effect) I also now use a low dose of something called Amlodopine that also brings this BP down, my current BP three weeks ago was 138/74 which is or seems OK, After every flight take a few measures or try Macallen, or Talisker, very good for calming the nerves and mind, don't know about BP though!!..
