It depends on so many things if someone had a few pregnancies gained/lost a lot of weight and went through the ageing process, your more likely to need them replaced.
My children are teenagers I wont be having any more children, I know I wont gain weight and I take care of myself and workout Id like to think mine will last me 10 years minimum but ill be 46 then so maybe in my 50’s I will need them redone but thats way off
