Folding mirrors on most cars fold relatively flush with the window glass. On the Q5, however, there's not much folding going on. It seems to swivel (as opposed to fold) and saves-what-something like 1-2 inches max.
If ground beef is refrigerated promptly after cooking (within 2 hours; 1 hour if the temperature is above 90 Â°F), it can be safely refrigerated for about 3 or 4 days. If frozen, it should keep its quality for about 4 months.
24 hours is fine. I've left ground beef in the fridge for about 2 or 3 days and it was still good. Raw meat should be kept at 40deg or lower and 3-4days is the standard. To prolong.......salt and spices and marinate it in a high salt marinate.....like steak sauces or soy sauce.
