Second-generation antihistamines cross the blood--brain barrier to a much lower degree than the first-generation antihistamines. Their main benefit is they primarily affect peripheral histamine receptors and therefore are less sedating. However, high doses can still induce drowsiness through acting on the central nervous system. Some second-generation antihistamines, notably cetirizine, can interact with CNS psychoactive drugs such as bupropion and benzodiazepines.

Safe-haven laws (also known in some states as ''Baby Moses laws'', in reference to the religious scripture) are statutes in the United States that decriminalize the leaving of unharmed infants with statutorily designated private persons so that the child becomes a ward of the state. ''Safe-haven'' laws typically let parents remain nameless to the court, often using a numbered bracelet system as the only means of linking the baby to the parent. Some states treat safe-haven surrenders as child dependency or abandonment, with a complaint being filed for such in juvenile court. The parent either defaults or answers the complaint. Others treat safe-haven surrenders as adoption surrenders, hence a waiver of parental rights (see parental responsibility). Police stations, hospitals, 24 hour convenience stores, Wal Marts, rescue squads, and fire stations are all typical locations to which the safe-haven law applies.
is it legal to drop a baby off at a fire station?

Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na ) and chloride (Cl ) ions). Average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at 4 C (39 F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about 2 C (28 F). The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured 2.6 C (27.3 F). Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.
