Can a cheap, over the counter pill, prevent the onset of ageing-related diseases and extend lifespan? I use the short-lived fish (9 to 12 weeks), Nothobranchius furzeri , as a model organism to test compounds for lifespan altering affects. Using my fish to quickly identify candidate supplements would save time in testing the different compounds on long-lived (3 years) mice and rats ; and instead research can quickly proceed to human trials.
