Investing in solar power can be risky. I wouldn't do it. Not at this time, when so many companies are going out of business.

Aging isn't smooth and gradual. There are, apparently two periods when people age quickly: around 44 years and around 60 years. Original study here. The study states that it is longitudinal, but in reality, the longest follow-up period was 6.8 years (for most, the follow-up was around 1000 days), so it is just assumed that individual observations at each age would be the pattern everyone would follow. This may not necessarily be true, as factors that affected one's life in one part of one's life may not be the same as that experienced by another population cohort of the same age. The population was mainly whites (65.7%) followed by Asians (20.4%), and genetics likely plays a major role. The scientists followed markers for cardiovascular health, ability to metabolize lipids, alcohol, caffeine, and skin and muscle-related markers. The raw data looks like a scattergram to me. it's hard for me to see the basis for the two age peaks.

The tech layoff stats are brutal. California got hit especially hard. Tesla's numbers may be in part due to their move to Texas. Layoffs at Dell alone probably account for over half of Texas' losses. But the U.S. bears the brunt of it all.
