The annual health-care costs for people who are extremely obese are almost twice those of normal-weight people. Very sobering is the fact that severe obesity is increasing at a much faster rate than moderate obesity, quadrupling from 1986â2000.6.
As a sea is connected to the oceans, which are salt water, most seas are also salt water. This is not a distinguishing feature between a sea and a lake, however, as lakes are more commonly freshwater but can be salty depending on their source and their surroundings.
A lake (in Scotland a loch and in Ireland a lough) is an area (prototypically filled with water, also of variable size), localized in a basin, that is surrounded by land apart from any river or other outlet that serves to feed or drain the lake.ne definition of lake is a body of water of 2 hectares (5 acres) or more in area; however, others have defined lakes as waterbodies of 5 hectares (12 acres) and above, or 8 hectares (20 acres) and above (see also the definition of pond).
