Re: What have you learned about aging?
No question that life expectancy will continue to increase in affluent societies. The big problem for medical science will be how to subdue brain-function so that there are exciting and new things of interest spread evenly throughout the whole lifespan.
Perhaps the solution lies in developing a 'controlled' form of Alzheimer's disease so that stuff always seems to be new and interesting. This will test the patience of generation-x, -y, etc, but keeping great-great-great-granny amused will not be high on their agendas anyway. Taking this to a doomsday conclusion, in a thousand years time we could end up with a whole alphabet of generations competing for the same space at the same time [ and on the same medication! ].
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
The 116th Congress is set to break records in term of diversity among its lawmakers, though those changes are coming almost entirely from Democrats.
- Women and nonwhite candidates made record gains in the 2018 midterms.
- In total, almost half of the newly elected Congressional representatives are not white men.
- Those changes come almost entirely from Democrats; Republican members-elect are all white men except for one woman.
