Thanks Paul, have enabled your testimonial. Have been considering removing the captcha puzzle from the forum and moderating the first 3 posts of new members. Sorry for any confusion as to why your posts didn't show up. Unfortunately forums are plagued by spammers aiming to direct search engines away from a site.
How did you find the captcha puzzle at login? Again it is set to 3 posts then removed from future posts.

One other question: Should I enable users to be able to delete their posts as well as edit them? My concern here is that if someone has a weak password, then another could get in and remove all of their posts.

That's okay I figured it was some form of monitoring for new members, and it's probably best to keep something like this as a security precaution anyway. I didn't have any problem with the captcha. It's been a while since I actually started using forums again so I don't really know how things work these days when it comes to the mechanics of forums. I would think its possibly not a good idea to allow any users delete their own posts, and if they want this done they should contact the moderator first to request it. Editing is usually something that would only need to be done to a new post that is fairly recent, so I don't even think one should be able to edit posts older than a few days, but then I may be wrong on this, and its probably best to have a member vote about all this.

A few years ago I was on a forum when one of the users had some sort of gripe with with an admin. He was an intelligent fellow and the topics covered were concerning ancient history, and he had posted lots of interesting information. Anyway he decided to leave the forum for good, but before he did so he removed all his older posts. I don't know how but the forum administrator didn't make backups or something, and all these posts were lost forever. After that time there were safeguards put in place so that a post could only be deleted if a valid request was made to the moderator, and editing a post was only available during a day or so, or again upon request.

Again, maybe its best to get an entire member vote on how they would like the site to work.
Hope that helps.
Paul.

Thanks Paul, I agree with keeping original posts, else all the valuable comments on that post would also be lost as you said. I added the monitor first few posts option in thinking it would be better than the captcha puzzle.

Found this picture....look at Page 35 ...

Of a pharaoh sitting on a forward tilted throne...looks just like Andrews recommendation for correct sitting!!

Yes its certainly making sense the more I look into IBT. The angle of sitting there is definitely better for me in the past when doing lots of computer work - provided my back was supported, otherwise it was painful for me after a while...but then I probably never walked around every 20 mins either lol.

Andrew...just watched Vernikos on the video you posted under your sitting article....she was a minute away from discovering IBT it seems but missed it. Does she know about it now though?? She elaborates quite well that the less we use gravity the sicker and older we will get.

Can someone point me to the video experiment Andrew did with finding the correct angle for complete circulation to occur in the tubes? I am trying to search the forum but too much other stuff coming up and don't want to spend time wading through irrelevant material.
Thanks.
Paul.

Doubt there is a video experiment for that one. He just explained that on a bed he achieved circulation in the tubes at 5 inches...then added an inch. Then found the Egyptian beds were also elevated to 6 inches.

Oh I see, well then he can explain it more. I am asking this in order to be more specific about angle at head height rather than top of mattress height (I mean length when lying down obviously). I am assuming he measured the exact angle of the tip of the tubes to be 5 degrees when best circulation is achieved.

If this is so then it means the top of our head is where we want to get a 5 degree angle for maximum circulation ideally, and not the top of the mattress. I am understanding of course there is a trade off between comfort and effect but just wanted to be clear for myself in that the tip of the tube is where he elicits the 5 degree circulation benefit in the tubes.

I just took some measurements from my bed. Its 74.75 inches in length, and its raised exactly 6.875 inches. This creates a degree at the very top of 5.26 degrees. However, at the point where my head rests at on the mattress, which is 7 inches below the very tip (67.75 inches), the angle falls to just 4 degrees.

Now I am sure healing is taking place at this degree for sure, but I would personally like to achieve the optimum angle, and if that is 5 degrees at the top of the tubes in his experiment, then that would equate to the top of my head when lying down, and not the tip of the mattress.

BTW, the maths I am using to calculate angles is as follows:-
6.875 inches raise divided by 74.75 horizontal length = 0.092 which converted by inverse tan function on calculator reveals the 5.26 degree angle.
At 7 inches below the tip the angle equates to 4 degrees as the inches raised there falls to 4.75 inches at the point I rest my head.

Sorry if I am being too exact in all of this, but I am just wanting clarification so maybe Andrew can clarify this himself.

I am a bit puzzled by why your bed and mattress are at different slopes....IBT has to be the whole bed at the same angle! Minus the pillows. Seems like you have enough slope. An inclinometer is sensitive to minute changes so it might appear different down the mattress.

They are not. My mattress is resting on a board with inclination starting from zero and rising to 6.875 inches at the tip (measurements have been taken carefully by taking into account thickness of board and where measurement was taken etc).
The difference in angle is always determined by the length of the horizontal run, which is the base where the mattress rests on and where ultimately the head rests on the mattress. The calculation I mentioned to determine the degree is obtained by where you measure on the length of the run, or even the actual mattress itself, which in trigonometry terms of these angles doesn't matter whether you use run or hypotenuse for length.
I had to recently learn this to determine the calculations of the angle, but I am sure Andrew knows exactly what I mean being from an engineering background.

You say " inclination rising from zero.." Surely you mean elevation height. Inclination is the angle. That doesn't change from tip to head. If the bed is straight. Point two. Your experience since July surely shows you have hit the benefit...and you are even going higher. The precision of measuring to two decimal places surely is irrelevant in this case. I.e. 4.75 degrees is as good as close to 5.

Yes I suppose I mean elevation from zero to 6.875 inches at the tip. Whatever word I used I still mean I get a full incline at the tip of 6.875 inches, and by using the maths calculation I have stated if means at the tip there is a degree slope of 5.25 degrees because its the highest point, but further down that slope to where my head rests its 7 inches further down the hypotenuse or base of where the mattress would be, and is therefore lower down elevation at this point, and using the maths again here means the angle is lessened to 4 degrees.

I am not a mathematician and like I said before I had to learn this recently so I may be getting something wrong here. Andrew comes from an engineering background so maybe he can clarify.

Yes it appears most likely that IBT at much lower angles than 5 degrees optimum does indeed help, but I would rather have the 5 degrees than the 4 degrees that my head rests at to get maximum results.

You are forgetting to reduce the length of your bed by the distance you move down...the angle does not change. The whole bed is at the same angle. The 7 inches down from the top should be subtracted from the length...then when you recalculate the angle should be the same angle you got at the tip. Easier is just to download an inclinometer append use that...smart phones have MEMS in them and a magnetic compass so we can measure angles directly. Andrew will comment but the maths is straight forward.

No I took that into account. These are the measurements below with calculations and results are same as I said...
Tip = 6.875 inches elevation at 74.75 inches so 6.875 / 74.75 = 0.092 and inv Tan = 5.26 degrees slope.
7 inches below this is 4.75 inches height at the 67.75 inches mark = 4.75 / 67.75 = 0.07 = 4 degrees slope.
I don't have a modern mobile so I am unable to use any apps. What is wrong with the above figures ?
Need help on this one because I understand what you say that angle should never be different, yet these are clearly showing a difference in slope angle...confused.
