Totally useless information/trivia

Kingfishers have extremely high mortality rates. Their young die in incredible numbers due to a variety of factors, including drowning when learning to hunt, nest destruction and flooding, and simply starvation. This means that only a quarter of their young make it to their first breeding season.

However even then only a quarter of those birds make it to their next breeding season. They are extremely vulnerable to temperature change and during winter or severe cold snaps many die. They have increasingly limited habitat due to development, contamination and pollution. This is then exacerbated twofold - they require more than half their bodyweight in food per day to survive, which the limited and damaged habitat makes difficult, and they are extremely territorial and live solitarily, meaning where there is good habitat it's limited in how many birds it can sustain. The contamination and pollution also means they're exposed to accumulation of toxins which ultimately kills them. They also get picked off by predators, and are susceptible, like all small birds, to vehicle strikes.

However, despite this high mortality, they are able to maintain their population.

They've obviously twigged that what is required is constant reproduction. Unlike pandas.

This is fantastic. Really highlights the difference between a few long term injuries and multiple short term injuries. 

Ronaldo, for example, being such a small circle but missing more days and matches than Reus who has had far far more injuries

Where’s Pogba? 

He'd be somewhere left of the Y axis.

He's missed 158 games, which would be high enough to make the chart, but he's "only" missed 843 days, which doesn't make the chart.

That's with 20 separate injuries

It’s crazy how much he will have earned whilst being unavailable to play.

He’s made 2 appearances for Juve since re-signing for them 9 months ago.

True of everyone on that chart to be fair

@Genie if Diaby earned an average of 50k a week (Google tells me he was on 65k a week at Arsenal) then he'd have been paid over £12m for the time he was injured

That chart has reminded me of a couple of things.

Diaby, despite basically never playing, seemed to score against us for fun IIRC.

And that Phil Jones still 'plays' for Manchester United. How on earth he's still got a contract for them I've no idea.

Attempting to beat Ken Warby's current water speed record of 317.596mph has a 100% fatality rate.

The record has stood since 1978 and since then only 2 people have made any attempt to break it. Both men crashed and died. Lee Taylor in 1980 and his wasn't even an actual attempt. It was a demonstration that went wrong. And Craig Arfons crashed in 1989 at over 350mph.

Problem with a water speed record is there's absolutely no margin for error, and you're working with a surface that isn't stable. Worst of all worlds.

Speed records on land are **** dangerous and that's done with a surface that we expect to be quite stable and flat, and where there's nothing to hit. Your main concern is rolling and we mitigate that with the design of the car, and provided nothing goes wrong you go very fast in a straight line and stop leisurely over a long distance.

On water you simply can't control it, so the design effort becomes about getting as much of the boat out of the water as possible, but not so much that it goes fully airborne, which gives you a margin that's razor thin and goes very wrong if you catch a ripple or wave that's that little too big. If that happens, it turns into a bad plane for a second and then you hit a brick wall at 300mph with limited protection.

One of those records that no-ones going to touch for a while.

Correct. Not just the ever changing surface but the resistance of water too and the power required to compensate for that. I watched this yesterday which is where I got the trivia from :D

Thanks - that'll be getting watched later.

Should have considered the power to resistance thing - it basically becomes unfeasible to generate the power to defeat the resistance to build speed. We'll need to come up with a different way of moving something through water to go much quicker.

A water based sonic boom would be fun/terrifying though.

Edit - apparently the sound barrier underwater would be something like 3000mph so yeah... That's one for the modelling software only.

Reminds me of our schoolyard black humour back in 1967 - "I hear they've renamed Coniston Water - to 'Campbell's Soup".
