Peace of the world is difficult. In Japanese history, a feudal lord tried to invade other asian countries. The lord was old, but succeeded in unifying the nation. During the course of invasion, the lord died because of illness. Soldiers are said to be reluctant to invade, but if they disobey the order of their commanders, they or their families would be tortured, bullied, or killed. So soldiers went to the other countries and caused great trouble to the people there.

Toilet for bedridden patient. For carers, it’s quit annoying being called by a patient at midnight. It’s quite important for caregivers to sleep a good sound sleep. They are suffering from shortage of sleep, daily physical labors of caring patients, and shortage of time to do their own work. If I miss to support the body of the patient properly, the patient will fall down and get hurt. So Carers have to deal with the patient very carefully.

There are some promising technologies that I’ve found lately. 1: iPS cell therapy According to the article on the website, the effect is already proven with mouse, but clinical trials for humans will be held from now on. https://newatlas.com/health-wellbeing/anti-aging-molecules-reset-cells-youthful-states/ https://karapaia.com/archives/52310900.html 2: Robot assisting walking rehabilitation system I wish I’d known this robotic system much earlier. https://www.irc-web.co.jp/lokomat# 3: Cultured meat https://en.wikipedia.org/wiki/Cultured_meat In Buddhism, there is a concept called karma. It means like “as a man sows, so shall he reap”.

Digitalization of old videos My dad is hospitalized and in a critical condition. I need to digitalize old videos of my family into files to be watched on an iPad. I’ve searched for some lost videos stored in drawers at home. I’ve searched for a VHS-C adapter to play VHS-C videos, but the place is forgotten at home. I’ve searched for some VHS-C adapter on the auction sites and found they are expensive.

Current medical technology can make clones of creatures. The clone becomes an Identical twin of the original one. We can ask a surrogate mather to give birth to a clone baby. Plants or single cell creatures propagate themselves with clones. Graft technology is possible with plants. There are Siamese twins. If an old man make a clone of him and graft it on him, then they will be Siamese twins. Or if we embed the clone into the the old man’s body like a pregnant woman, it will grow inside of his body.

I’ve finally got a vaccination against corona virus. The effect was heavy. What I realized after getting the vaccination was that I’ve just underestimated the virus. During this pandemic, I went to public places many times wearing masks. I thought that I was sturdy enough to repel the virus. But after getting the vaccination, I had suffered from terrible symptoms of the vaccine. I felt killing chill. I spent night gasping all night sweating soggy in my bed.

Drone One of my dreams is to fly in the sky freely. Now drone is getting popular these days. They use VR camera to watch the scene from the drone. Instead of VR camera, I’d like to propose a way to use 360 degrees camera. Not only one screen ahead, but also cameras on both sides, up and down, and behind your body. Then you will feel like you’re really sitting in a cockpit of the drone.

I’ve worked as a delivery worker of Uber Eats and Demaekan. I bought a bag below. When I bought it, it costs 4000 yen. But now the price is increased. But perhaps you can find a web site that sells it with 4000 yen. The bag was useful but heavy. It can hold PET bottle to drink water with a net beside it. It was a good point, but to tell the truth, I didn’t use this bag to put foods in it.

My dad is suffeing from a disease called progressive supranuclear palsy: PSP. Nowadays, I’m caring my parent everyday. Caring disabled is hassle. He is very heavy to support. He can’t keep his balance. I need to control his balance when I try to make him walk. He is almost bedridden. But I think that walking with his own foot is quite important. To keep standing while feeling vertical stimulation of gravity strengthen bones and stimulate the secretion of some proper hormon, I guess.

Fail safe traffic system. It’s technically not difficult to make such system with the current technology. I wonder why people won’t make it immediately. People are facing aging society. Elderly people are prone to make mistakes while they are driving. So the possibility to see such tragedies won’t be reduced if we don’t do anything. Install communication devices into every vehicles like number plates or regular automobile inspection. Install passive controller of speed and steering into all vehicles.
