Sometimes weird things come through my Google searches based on suggestions. I had been doing some safety searches for a friend when “LD 50 Caffeine” came up in the suggestion box, so I clicked on the suggestion.
Death from caffeine ingestion appears to be rare, and most commonly caused by an intentional overdose of medications. In 2016, 3702 caffeine-related exposures were reported to Poison Control Centers in the United States, of which 846 required treatment at a medical facility, and 16 had a major outcome; and several caffeine-related deaths are reported in case studies. The LD50 of caffeine in humans is dependent on individual sensitivity, but is estimated to be 150–200 milligrams per kilogram (2.2 lb) of body mass (75–100 cups of coffee for a 70 kg (150 lb) adult). There are cases where doses as low as 57 milligrams per kilogram have been fatal. A number of fatalities have been caused by overdoses of readily available powdered caffeine supplements, for which the estimated lethal amount is less than a tablespoon. The lethal dose is lower in individuals whose ability to metabolize caffeine is impaired due to genetics or chronic liver disease. A death was reported in a man with liver cirrhosis who overdosed on caffeinated mints.
That means by the time I get close to even a harmful dose of Vitamin C2 my kidneys are already flushing it out of my 190 pound (86 Kg) body. I might damage my kidneys, but I wouldn’t be in mortal peril from drinking as much coffee as I could chug. My liver has been tested several times during drug evaluations, and as the family joke goes when I die they are going to have to beat my liver to death with a stick. I have several now-deceased relatives who were legendary drinkers with high alcohol tolerance, but who never-the-less not alcoholics as they could go months without drinking to no obvious ill effects, between drinking sessions that would have killed others from alcohol poisoning, also with no obvious ill effects. I have never seen any need to emulate their feats, so my own tolerance is still in question. Mind you these were all relatives on my father’s side, mostly related via my grandfather.
But this is secondary to my coffee consumption, which is currently running about a liter per day. At that rate I will live forever as far as dangerous amounts of caffeine are concerned.
…In the background of a web comic. The scene was in a coffeeshop in Anchorage AK, and a small advertising poster said “Coffee, the WD40 of adulting”. I wouldn’t go that far, because I also use other sources of caffeine, and I’m not generally homicidal before coffee. Other times, yeah, but the level of caffeine in my blood is only a tiny piece of the puzzle for instigating homicidal rage. Now I’m not going to say it’s safe to push my buttons prior to coffee, because if you’re pushing my buttons prior to coffee, you already did something to make me angry just by being there.
Also something has updated on my site and the text is eyestrainingly small on posts. I didn’t do it so I don’t know how to un-do it. Just know that I don’t like it either and I’m trying to fix it. And I just bumbled around and fixed it in the font settings for the post, which I hope sticks for all the posts.
I have been neglecting the model version of the Sprint-T in favor of trying to fix the handling problems inherent in the design of the TGS2. I mean I know I should be doing something on it, but the inspiration has been lacking compared to the TGS2 and posting in the blog.
After it quit raining Sunday evening I went for my walk and picked up a bag of cereal. Yes I’m cheap and buy the bag cereal. It’s slightly cheaper per ounce than the box, we just don’t always have the $ to pay for a bag. I also get PopTarts in the big box except when the sales on the small box makes them cheaper per breakfast. Why cold cereal and PopTarts for a grown man’s breakfast? Simple, those are relatively non-lethal to prepare when I’m pre-caffeine. Cognitive functions generally don’t kick in until the second half of the cup, and it’s much safer to have things that don’t require the use of the stove or anything more complex than pushing the lifter down on the toaster. Even the measuring out of the various ingredients of my cup of coffee have become mostly autonomous. I can’t quite do them in my sleep yet, but I’m close. It’s when things change like switching from milk and sugar to pre-sweetened creamers that stuff gets messed up. More than once I took a swig of what was supposed to be coffee and got a slug of liquid candy instead. And for some reason that stuff just seemed to get sweeter and sweeter during the day. A few hours after pouring my coffee in I felt like pouring it out.
Speaking of my walk, it was so humid after all that rain I could have almost gone for a swim instead. It was 71°F with a 70° dew-point. UGH! sticky! At least it wasn’t hot to go with that sticky.
I would do more writing but my neck and shoulder are starting to bother me and make it hard to type.
Yes, there is a direct correlation between creation of a blog post and the presence of coffee. One is required for the other, but the reverse is not true, presence of coffee will not guarantee a blog post, there are other things involved as well, but there will not be a blog post without coffee. Lots of coffee. One of the other things required for a blog post is information. I guess I could make like the infinite monkeys typing on an infinite number of keyboards, but I don’t think anyone would be interested in proofreading the output of that. So before you see a post here, at a bare minimum there are three things needed: 1. Me, 2. Coffee, 3. Something from the Feed. If you are reading this post then you can assume that those minimums have been met. If you are note reading this post, what the heck are you doing?
First up is another SWCC from the cyclist’s death trap town of Chattanooga TN, where killing a cyclist is legal as long as you can say you didn’t see him. Police Say DUI Cyclist Hit by Car Don’t drink and ride your bike. Don’t ride your bike in Chattanooga without audio and video documentation of whether or not the driver saw you. LEO there don’t care if cyclists live or die.
A warning on ignoring maintenance of an assisted bicycle, especially the kind with front wheel hub motors. Motorized bicyclist’s injury leads to Medflight to Lee County Hospital For those of you not familiar, breaking the fork dropouts is a common failure mode for front wheel hubmotors. This can be avoided by routine inspection of the mounting of the hubmotor to insure that the axle is not rotating in the dropout, which will lead to the eventual failure of the dropout. This can also be prevented by use of a torquearm to restrain the axle from rotating. Breaking a dropout causes the front wheel to separate from the bicycle, with predictable results. I am a firm supporter of assisted bicycles, but like any mechanical device they have their own maintenance issues that must be dealt with to be safe. A regular bicycle is no different in that regard, and neither is a car.
A cyclist injured in OR is recovering from her crash. Injured cyclist gratefully makes strides in her recovery “She darted out within feet of me, and she kept coming,” Davis told police, according to the report. “I swerved and drove while hitting my brakes.” His wife, Melanie Davis, was talking to the couple’s two children in the back seat and did not see the collision, the report says. Melanie Davis said her daughter “saw the bicyclist ride in front of their vehicle from the right. When she saw the bicyclist coming, she screamed and her dad swerved to the right.”So when something is coming from the right, you just swerve into it? And even in a state like Oregon where bicyclists are a major share of road trips in urban areas, the cyclist is at fault for getting hit from behind. TANJ!
And that’s all I had today.
