The habit of frugality: Most self-made millionaires do not buy new cars. They wait until a good quality car is about two years old before they buy it. They buy the car and then drive it for five or ten years before replacing it. [2004] - Brian Tracy

96 percent of all businesses fail within 10 years, with 80 percent failing within the first two years. The top reasons for failure include bad customer relations, bad budgeting, lack of staff training, failure to anticipate market trends, and poor and inconsistent marketing. [2007] - Chet Holmes

If you're investing in major markets, there is no more space to build at the same time as there is a net migration into the cities. Simple supply and demand stipulates that prices will remain robust (taking into account the inevitable corrections) for the foreseeable future. [2017] - Calum Ross

People practicing Zen meditation, or loving-kindness meditation, have longer telomeres than nonmeditators. A range of mind-body activities--Mindfulness Based Stress Reduction, yogic meditation, Qigong, and intensive lifestyle change--all promote better telomere maintenance. [2017] - Elizabeth Blackburn

The Galleri test looks at methylation patterns of the cell-free DNA, which are basically chemical changes to the DNA molecules that suggest the presence of cancer. In a study, the Galleri test proved to have a very high specificity, about 99.5%, meaning only 0.5% of tests yielded a false positive. If the test says you have cancer, somewhere in your body, then it's likely that you do. The trade-off is that the resulting sensitivity can be low, depending on the stage. (That is, even if the test says you don't have cancer, you're not necessarily in the clear.) Keep in mind this test still has much higher resolution than radiographic tests such as MRI or mammogram. Those imaging-based tests require "seeing" the tumor, which can happen only when the tumor reaches a certain size. With Galleri, the test is looking at cell-free DNA, which can come from any size tumor-even ones that remain invisible to imaging tests. [2023] - Peter Attia
