Seems like an expensive, impractical and non-commercial viable version of Boom Supersonic (if their hype is to be believed...)
Would be curious to know how much they've spent vs Boom
Sounds idyllic at first but it seems like it would get extremely lonely very quickly.
During the pandemic I used to watch all of those van-life youtube nomadic channels and fantasized of doing such a thing. After a week of driving through Iceland, I quickly realized it's nice to have a bigass bed, kitchen, couch, flatscreen etc.
In a randomized crossover trial, 75 young adults (healthy weight, overweight or with obesity) consumed a drink containing sucralose, sweetness-matched sucrose or water. We show that acute consumption of sucralose versus sucrose stimulates hypothalamic blood flow (P < 0.018) and greater hunger responses (P < 0.001). Sucralose versus water also increases hypothalamic blood flow (P < 0.019) but produces no difference in hunger ratings. Sucrose, but not sucralose, increases peripheral glucose levels, which are associated with reductions in medial hypothalamic blood flow (P < 0.007). Sucralose, compared to sucrose and water, results in increased functional connections between the hypothalamus and brain regions involved in motivation and somatosensory processing. These findings suggest that non-caloric sweeteners could affect key mechanisms in the hypothalamus responsible for appetite regulation.
Seems sucralose makes you hungrier than sugar water, but not more hungry than water... obvious question is whether most will over-eat the ~140 calories in a coke. Coke vs water is obviously worse...
I thought the whole point of starlink was that you can use it anywhere... I'm surprised they're restricting purchases by home address.. maybe you can register using a friend's address?
Can't wrap my head around does this make the Ghibli IP more or less valuable? Seems like their original merch for Totoro etc will be more valuable and if they release a future movie it might make them more popular.
If you're a human depending on your looks as a model without influencer status things are looking grim...
~6.75% or so I think. It can't be zero or no one would ever pay them off. But it should track closer to federal interest rates and you should be able to write off the entirety from your taxes.
As someone who has paid off >300k in loans I have empathy for so many of these students. So many were fed lies as teenagers about the returns of college and are stuck in dead end careers with insurmountable loan payments and a balance that won't go down. A lot of the stories on /r/studentloans are depressing and many are suicidal.
