i always had a 300 PFT score when i was on active duty our gunny put me in charge of the remedial PT for my workplace the biggest problem i saw was people not getting their breathing rhythm properly once i was able to get them to do that correctly they had no problem running and i helped out some serious fatbodies <| sep |> Oh I was wondering if it would brakeMore effectively at different speeds that makes sense <| sep |> please go to this link and read the very first commentI assume that you talk about Jon McIntyre comment . It ' s exactly the same thing that you said . Let me quote a few lines What I find very curious is the complete absence of any discussion about how to construct a test that would be accurate , comprehensive , and conclusive . That is simply not true . There are lots of comments explaining why his experiment is not precise enough and how it could be improved . There are lots of comments everywhere providing experiments that are better suited to measure the curvature of the earth . The thing is that Jon Mcintyre simply censored the constructive comments on his channel . He did exactly that with my comments , saying I have to look out for my less mathematically sophisticated viewer who may be swayed by your false information dressed up as being true . sic . I hope you can appreciate how twisted this is . And we could easily design and complete a test that would be 100 % conclusive to the point where almost nobody would argue the results . We could , we have , uncountably many times . A few people still argue . The problem is not about evidences . It ' s about people , not understanding how science works , not trusting other people , and listening only to what they want to listen . we can devise a proper method for measuring the shape of the surface of the earth . Of course we can . Very easily . And we did uncountably many times , starting 2300 years ago in ancient Greece . People still argueThe problem is not about the method . It ' s about people , not understanding how science works , not trusting other people , and listening only to what they want to listen . This is the first time we can actually put a conspiracy theory to bed . I think this is a very important thing to understand . The reason for which NO conspiracy theory is ever put to bed is because PEOPLE want to believe . It has absolutely nothing to do with the amount and accuracy of evidences that you present . So even if Jon McIntyre perform an experiment that convince him that the earth is round , there will always be people that will doubt it . People that will say that Jon was a globe earther shill from the beginning . People that will say that his measurements are off because of whatever reasons . People that will simply not look at a 5 minute video proving that the earth is round , but will look at 500 proofs that the Earth is flat for several hours . At some point you have to realize that the problem does not come from the evidences . The problem comes from the fact that either you don ' t understand these evidences or you don ' t trust them . I can help with the understanding , but I cannot help with the trust . That ' s why I ' m saying that you should do experiments yourself . And that you should learn a little bit of geometry yourself . So that you won ' t have to trust anybody but yourself when you get the results of your experiment .
