Charles Darwin was born into a moderately wealthy family in Shrewsbury, England. His father, Robert, had the largest medical practice outside of London at the time and his mother, Susannah Wedgwood, was from a family of wealthy pottery manufacturers.
Advice from different manufacturers varies considerably. In my Neff fridgeâs instruction book it advises only, âat least half an hourâ, which is surprisingly low. A Smeg fridge freezer instruction book says, âlet it settle for 6 hoursâ.This 6 hour recommendation is increased to 24 hours if it is known that the appliance has been laid down.t the end of the day, the last thing you want is a system blockage. If you had to temporarily tip the appliance over to get it through a door or off a vehicle then you need to let it stand for longer than if it was kept upright constantly. If you know itâs been laid down leave it for 24 hours.
Timing Is Everything. Indoors, you can safely leave a sandwich out for up to two hours after making it, according to the USDA. After that, bacteria starts to multiply rapidly. In hot weather the margin of safety is cut to one hour. Don't take chances. Refrigerate sandwiches or pack your lunch box with an ice pack.
