Calculating LEV
To estimate the LEV, researchers have proposed using a "break-even point" analysis. This involves estimating the time it would take for life extension technologies to improve human healthspan by a certain percentage, such that the benefits of the technology outweigh the costs.
One way to calculate LEV is to use a rough estimate of the rate at which life extension technologies will improve human healthspan. For example, some researchers have suggested that life extension technologies could improve healthspan by 20-30% every 10 years. This would result in an exponential increase in healthspan, leading to a potential LEV.
