You can check your owners manual scheduled maintenance section. Timing belts need to be changed at a scheduled service interval. They range anywhere from 60,000 miles up to 105,000 depending on the vehicle year, make, model and engine type. Timing belts should also be changed BASED ON TIME.
Bacon can also be frozen safely for 6-8 months. The shelf life of bacon depends on a variety of factors including the sell by date, the preparation method and how the meat was stored. Bacon is tasty for breakfast, lunch, dinner or as a condiment. Just like ham, it is a cured meat prepared from a pig.
I think chicken in the frig uncooked can last up to about a week anything past that will be spoiled chicken lasts longer in the freezer til you're ready to cook it. Chicken is best used within 2 days after thawing in the fridge. However, it will have a slightly different smell/odor if it is too old. Below I included a link that explains thawing times and methods for Chicken. I think it will be of great help in a lot of different chicken areas.
