Kdy\u017e jsem se zm\u00ednil o \u017eivotnosti, tak se uv\u00e1d\u00ed vlastn\u011b dva druhy \u017eivotnosti a to po\u010det sepnut\u00ed a \u017eivotnost sv\u00edcen\u00ed v hodin\u00e1ch a proto je vhodn\u00e9 vyb\u00edrat dle toho, kam bude led \u017e\u00e1rovka ur\u010den\u00e1, tedy t\u0159eba na toaletu, kde se bude \u010dasto zhas\u00ednat a rozsv\u011bcet, bych volil led \u017e\u00e1rovku, kter\u00e1 bude m\u00edt co nejv\u011bt\u0161\u00ed po\u010det sepnut\u00ed a na opak do ob\u00fdvac\u00edho pokoje se zase hod\u00ed led \u017e\u00e1rovka s\u00a0 del\u0161\u00ed \u017eivotnost\u00ed dle sv\u00edcen\u00ed.<\/p>\n
