The heat waves seem to have subsided again but I am now ravenously hungry at the same time as having no appetite. I could eat a horse, but I don't want to. Especially as we are going swimming this evening and I don't like swimming on a full stomach. Also, I am sitting in a cool breeze from the conservatory that seems to be helping. My torso and shoulders feel incredibly stiff, however - actually, thinking about it, this happened yesterday as well, only for the entire system to descend into spasmed flaring late in the evening. My head still feels clouded and dull, and I'm having trouble with motor co-ordination and words. Must remember to enter that into the diary. Of course, this could be the low phase of the carrier wave, as I'm still getting pain spasms and tiny little hot flushes which are confined to the spinal area between my shoulder blades. The hot flushes are accompanied by stiffening in my arms, I can feel it in the line down the outside of the forearm along the bone.
Last night it started going poo when it felt like my vertebrae were trying to grow spikes up out of my back. I will have to keep an eye out for that (but not literally, heh).
12:11
Trying to remember last night's dreams. They seemed to be a follow-on from the previous night's, but I can't remember much more than the decor of the house some of it was set in (white walls, open ground floor with two-level wooden flooring and a decorative arch on the ceiling separating the living area from the dining area). Not feeling too chipper today, although I managed to give the impression of being a happy, sociable bunny when we went out to dinner last night at our friends' house. Frood had to cut Sam's (the other one) and Simon's hair.
Incidentally, I'm dead chuffed with Frood's latest addition to his site (he's even less technically competent than I am and I do his html for him. Sorry about that font, he insisted). That turned out really nicely and I keep going to have a look at it.
Don't like having to do the happy sociable bunny thing, but I get the feeling if I stayed home every time I feel like crap when we are due to go out, I would never get to go out at all. Can an illness be like a dog? If I give in and stayed behind and moped would it learn that it can succeed and keep making me feel shitty when I'm supposed to go out?
Ghods, rambling now. Utter rubbish. I'm starting to sound like the doctors who keep telling me it's all in my head. Bastards. Still, Tom Baker hasn't said that to me yet.
I hope I don't call him Tom Baker to his face. No, I'd call him "Doctor", and that's ok, even if he doesn't have a very long scarf. Or jelly babies.
Just reread what I'd typed looking for mistakes and read "moped" as "mo-ped". Pain in my legs is making my thoughts erratic and disjointed. Or maybe it isn't, it's just coincidental with it. Everything feels jerky, like reeling in a big fish.
Hour and a half until I have to meet Sam (the other one, Frood has two Sams - a brace, by Bellamy. Bellamy! Bellamy!) at Touchwoods (no website, maybe I should do one for them) and help him choose a tent. What else did I agree to do last night after they started feeding me Pouilly Fumé? I think I agreed to do Jodie's spreadsheets for her, but that was given anyway. I think I did the "looking at people and telling them what's wrong with their back and why" game. Fiona had a fit when I told her she had crampy feet.
You tell them it's down to posture, which they accept, even though it's blatantly obvious you can't tell a person has crampy feet by looking at the way she is sitting. They would accept that explanation over the more accurate one. Sometimes people confuse me. Sometimes I'm not sure I want to be people any more. Sometimes I know damn well that I don't want to be people any more. Land was so much more soothing.
Turning aphasic. Having trouble matching letters with sounds and concepts. Words keep splitting apart into component parts. Got to keep a hold of this. Can't give in and lost my head now.
Ghods it hurts sometimes. you know. Running very hot.
Distraction. Neutral buoyancy, dear, is a matter of practise. Practise and good breath control. You wan to learn scuba diving, cheat, use a stab jacket. Must get mine serviced before September. And my DV. Or did I just give that to my other brother? Can't remember a damn thing any more. Ha. Supposed to have perfect memory. Not these days.
Oooh. Ow. That's new. Blunt knitting needle up into behind forehead through upper right quadrant of left orbit. Not had that particular type of torture before, and it's interfering with my vision. Hoorah.
Neutral buoyancy. It's all a matter of Avogadro's principle, you know. No. Not Avogadro, he was something to do with moles (no doubt eating spicy noodles and chick peas was his idea). Archimedes! That's the one. Turn of the screw, and all that. Archimedes principle is all about displacement of mass.
You can do this in the bath. It's why boats float. They say he discovered it in the bath.
A body in fluid will experience an upthrust equal to the weight of the fluid displaced by the body.
The bit that used to get the slower members of the class was that it's the weight of the fluid that is important, not the body (although that is also important). it's also why I occasionally ask winged Otherkin types what the air composition/density and gravity is like where they come from. Just because. Archimedes. What a groovy guy.
Anyway (why am I doing this? Not the giggling hysterically but the explanation of Archimedes. Anyone remember? Care? No? Fine). Anyway. What you need to do is work out the volume of your body. This is quite difficult when it comes to people, sadly, so start with something simple. Once you know the voume you can work out the weight of fluid it is displacing. So if you have a volume of 1 litre and you are in water, you are displacing 1kg of fluid. Now, if your body weighs more than 1kg it will sink. If it weighs less than 1kg it will float. If it weighs exactly 1kg you have achieved neutral buoyancy. Hoorah!
People are, basically, big bags of mainly water (according to an alien species in Star Trek anyway), but not just water. And there is the complication of gaseous inclusions of variable volume. Lungs and stomach and things. These things change not only a person's volume, but therefore person's density (where density is mass over volume). So on the one hand you have the extra weight caused by not being totally water but having solid bits as well and other things that are denser than water, but you have the reduction in weight from having big bags of air inside you. This is why most people can float to some extent if they have lungfuls of air.
Now we have to start thinking about pressure as well. At higher pressures the same amount of gas takes up less space (is that one Boyle? I always get the gas laws confused. pV=nRT and all that stuff). So. Achieving neutral buoyancy, dear brother, in the deep end of the swimming pool, is all about being at exactly the right depth with exactly the right amount of air in your lungs. So the point at which you achieve neutral buoyancy can not only be variable depending on how much air you keep in your lungs and how far down you go before trying to achieve it, but also variable according to what your digestive system is doing.
But you knew all that already.
Still. I think the worst of the brain meltdown threat has passed now. I need a cup of tea.
