The reality is is that these hosptial visits are going to become more and more frequent until the Duke passes. It's unavoidable.
The Duke's health is on the decline and it's evident his immune system is continuing to weaken. Both a sign of his age and the natural wear and tear on his vital organs and respiratory system.
I should hope the Duke returns to Balmoral very soon, and is able to enjoy the remainder of his time there. He does need alot of rest and it's high time he be told by his physicians in no uncertain terms that his public official engagements need be dramatically reduced and more time spent on personal recreation and leisure. Doing what makes him happy.
And what's more is that when looking at photo's of the Queen over this past year, she appears to have aged quicker than I have ever noticed before. In part, I would endeavour to suggest that she is consistently anxious about the health of her husband. In my opinion, It's more than the look of concern, it's the look of a wife fearing the prospect of what lay ahead. The mere concept of a life without Philip must leave her with a sense of great uncertainty, and understandably so after almost 65 years of marriage.
I think it's starting to hit home now, more than ever before.
