In summary, existing literature supports the use of cigarettes to enhance endurance performance through weight loss and increased serum hemoglobin levels and lung volumes.
...people were nearly a year-and-a-half younger
after listening to “When I’m Sixty-Four” (adjusted M = 20.1
years) rather than to “Kalimba” (adjusted M = 21.5 years),
F(1, 17) = 4.92, p = .040.
Length of stay in hospital and duration of fever were significantly shorter in the intervention group than in the control group (P=0.01 and P=0.04, respectively)...Remote, retroactive[emphasis added] intercessory prayer said for a group is associated with a shorter stay in hospital and shorter duration of fever in patients with a bloodstream infection and should be considered for use in clinical practice.
I will tentatively suggest that the difference reported is about people hearing music which was popular when they were younger than about the details of the music.
Cigarette smoking: an underused tool in high-performance endurance training
musical contrast and chronological rejuvenation
Effects of remote, retroactive intercessory prayer on outcomes in patients with bloodstream infection: randomised controlled trial
The music link doesn’t work.
I will tentatively suggest that the difference reported is about people hearing music which was popular when they were younger than about the details of the music.
