Vishen Lakhiani explains that even small late-life changes work fast. Sedentary 75-year-old women gained 800% strength in six weeks. People over 80 who start walking or climbing stairs see rapid improvements in health and strength.

The interesting thing about peak performance aging is if you look at the data, two things are very true. First one is that peak performance aging starts young. So there's stuff in your 20s and your 30s and your 40s and your 50s really matter. Second, interventions even incredibly late in life really matter. It's shocking the improvements you can get in strength. The researchers are like we don't understand what we're looking at, right? We had sedentary 75 year old women who hadn't moved in 20 years and in six weeks we saw a 800% boost in strength. What the is going on here that's really common, these late in life interventions. In fact, there's studies that show that if you're totally sedentary and over 80 and just go from like totally sedentary to I'm now going to climb stairs instead of taking the elevator, I'm going to walk to the store instead of driving those kinds of interventions, you immediately start getting health and longevity effects.
