if a particular individual prepares food for a meal rather slowly, that individual may allow a more liberal amount of time in which to do so without having transgressed "borer." Examples of Permissible and Prohibited Types of sorting/purification: Peeling fruits: Peeling fruits is permissible with the understanding that the fruit will be eaten right away. Sorting silverware: Sorting silverware is permitted when the sorter intends to eat the Sabbath meal immediately. Alternatively, if the sorter intends to set up the meal for a later point, it is prohibited. Removing items from a mixture: If the desired item is being removed from the mix then this is permissible. If the non-desired item is being removed, the person removing is committing a serious transgression according to the laws of the Sabbath.

The laws of medicine use on the Sabbath are complex; they are based around the kind of illness the patient is suffering from and the type of medication or procedure that is required. Generally, the more severe the illness (from a halakhic perspective) the further into the list the patient's situation is classed. As a patient is classed as more ill there are fewer restrictions and greater leniencies available for treating the illness on the Sabbath. The list of definitions, from least to most severe, is as follows: / Mayḥush b'Alma / Minor Indisposition / Mikṣat Ḥoli / Semi-illness / Ṣa'ar Gadol / Severe Pain (Can in some cases be practically regarded as level 4) / Ḥoleh Kol Gufo / Debilitating Illness / Sakanat Aiver / Threat to a Limb or Organ (Can in some cases be practically regarded as level 6) / Sofek Pikuaḥ Nefesh / Possibly Life-Threatening (Practically treated as level 7) / Pikuaḥ Nefesh / Certainly Life-Threatening For most practical applications the use of medicines on
