I always just use a cold stick of butter like a crayon. Grab the hot toast and wipe the butter on it straight from the stick. Butter knives are only for room temperature butter.

Well, your showerthought post was basically rich people cause suffering and climate change. It’s true they generate a hugely disproportionate amount of CO2. But my point (and maybe it wasn’t clear) was that when there is an easy energy resource just sitting underground, it’s going to get used whether by rich people or not. It provides too much of an advantage. Having coal and oil at your disposal is like having a near endless supply of free workers. One liter of gasoline, when used in an engine, produces roughly 2 to 4 kWh of mechanical energy, equivalent to the daily labor of about 100 people. No society is going to turn down that many guiltless slave workers. We were told 100 years ago it was going to cause climate change, but we didn’t have the technology to replace it with electric at the time. Effective batteries are a recent invention. So there really was no alternative. Your neighbor country is making use of millions of ‘energy slaves’ and growing their population like crazy. Are you going to continue plowing your fields with donkeys and hoping you can feed your people? No, using that energy was inevitable.

And now? Theoretically we could replace our energy infrastructure with renewables. In the US it would take at least 5 trillion dollars and who knows how long and how much energy to do it. But I don’t think it’ll stop climate change. Call me a doomer, but I think it’s already too late for that. We’ve already released enough CO2 to kill the planet. The effects just take about ten years or more to show.

Sure, we want to blame climate change on the fossil fuel industry, the capitalist owners thereof, the big industries, long haul ocean shipping, etc. But I don’t think it’s realistic. Imagine the situation a few hundred years ago. We burned wood to keep warm in the winter. We cut down forests and pre-burned them in vast quantities to make charcoal which we then used in smelters to make iron and steel, in kilns to make pottery and glass, in steam engines to turn all sorts of things. We were on track to cut down every tree on the planet to use for one of those things. Then we found fossil fuels. They were better than wood in every way, except that the generated CO2 wasn’t renewable. Any nation that used them surged ahead of all others in productivity, defense, offense, and quality of life. To refuse to use them, even if you knew they would kill us all a few hundred years later, meant that you got outcompeted, and probably overrun or conquered. There was no option. So everyone used them more and more. That’s been the story ever since. It’s a Faustian bargain. You get comfort and success now and someday your ancestors will suffer. But you figure that they will be smart enough then to solve the problem so you don’t worry about it. Yes, our economic system guarantees that a small number of people will profit from it the most. And they will make it worse one way or another. But climate getting worse just a matter of time. Even if we had the most enlightened people making decisions for us who would agree when they said we all had to stop using fossil fuels? There is almost nothing you use in your life that isn’t made with fossil fuels somehow. And it’s too late now. We can’t go back. We can’t all be subsistence farmers. There are too many of us. We can’t survive without fossil fuels.

tl;dr - yeah, the capital owners are awful, but climate change would have happened without them.

I’m 57 and I started running this year. Overtraining is the biggest issue for me. I’m up to about three miles maybe four times per week, but most of those miles are zone 2 HR, really slow and easy runs. On the weekend I’ll do a tempo run, or intervals, alternately. If I maintain that schedule for more than a month or so I end up a little more sore every time I go running and my time starts to drop. So I have to take most of the week off every four or six weeks. I also take a lot of supplements; creatine, L-carnitine, Beta-Alanine, protein, etc. They help. I feel I can exert myself more since I started taking them. I also take EFAs for joint health, collagen for connective tissue recovery, and sometimes MSM, though evidence on that one is spotty.
