or something. So I'm not so sure this study is telling us what we think. However, I'm a big fan of people being useful. So yeah, having a sense of purpose is so highly recommended for your mental health, it doesn't surprise me that it might be correlated with your physical health and your dementia. So I would say even if you're not positive it works, it's all good if you can find a purpose in life.

Popular Science tells us that some big companies, I guess there are 4,000 buildings now, have used this technology which is that they use cheap electricity at night to make a bunch of ice and then they use the ice to cool the building during the hot summer days. And I guess the technology works and it saves a bunch of money. You just need room for an enormous pile of ice somewhere in your basement, I guess. Though it would make more sense for the ice to be on the roof, wouldn't it? I don't know. So now you've got ice that they're calling it ice batteries, but it doesn't store electricity. It just stores the coolness, which can be released to supplement your HVAC.

Japanese researchers have figured out how to use quantum entanglement to boost robot posture control. Now, that to you sounds like not a big deal. But if you notice how no matter how good the robot technology is over the last 25 years that the robot is always a little slow. Have you noticed that? Like there's just some lag or something. But apparently using quantum computing which can simultaneously deal with lots of possibilities at the same time. So I guess a regular robot has so many moving parts that affect other moving parts. Like if it's walking, it kind of has to get every part of the robot involved. So it's hard to coordinate all that stuff and to do it quickly. And part of the reason
