49:18 Well, yeah. You have sensor readings and things like that.
37:12 Because I mean, back way back in the day in the, you know, forties, fifties, and sixties, you know, cars were really only designed for 3, 4 years max. If you got, like, 50,000 miles on a car, that was a lot of miles for a car back then.
41:55 Yeah. So so what I first said is more of, like, the design equation side, and now you wanna know more, like, exact nitty gritties kind of things. So so, obviously, you pick components that you know are less temperature to have less of a temperature dependence and have nothing that can dry up and have really good aging parameters. So film capacitors as much as possible, things that are potted. If you if if you have something that is embedded in urethane, a lot of times that has a longer lifespan, Things that, resist vibration, things that resist temperature swing
