To me, without any further digging, Saturn retrograde in the 6th is just a problem. More so opposing Venus in the 12th. And in general, dynamic 6/12 with a heavy planet involved, especially retro is a bad sign. I've been looking in three charts recently, all belong to friends, all have Saturn in 5th retro, and all can't have children, for different reasons. One has no medical issues but something always goes wrong with partners. He's approaching 50 and starting to lose hope. Second has no medical issues but ehr partner does, she loves him, doesn't want to separate, he doesn't want to treat himself and argues with doctors. Third has medical issues and can't resolve them for now even with today's medicine. Three different stories but the result is the same. So, to me, Saturn retro has proven to be quite tough wherever he is in the chart. This man has him in the 6th, and if we take traditional rulership of Saturn over the Ascendant which happens to represent the overall well being of a person to me, including body, things don't look very well. Mars retro is conjunct the 8th cusp, not a good sign either, inconjunct the Sun which to me represents the person's vitality and self, even worse. However, based only on the natal chart, I doubt I'd have seen him dying young, I'd have seen the health issues. But I'm one of those who believes death is generally beyond our senses, in all kinds of divination and I don't try to predict it, ever.
Yes a better choice of words would be that I was 'not surprised' to see that he died young given the condition of Saturn and Mars. However the availability of good medical techniques can indeed make a major difference to the actuality (or lack of it) of death compared to the potential of death - which I, if any one, should know LOL.
However, that being said, Wadlow died as transiting Mars, was about to perfect the conjunction with natal Saturn, in a Scorpio/Leo/Aries/Scorpio period in terms of Releasing from Fortune. - that's Mars/Sun/Mars/Mars plus transiting Mars. The Lot of Fortune having relevance to what befalls the body
