Nemôžem vytvoriť súhrn tohto článku, pretože v poskytnutých výsledkoch vyhľadávania sa nenachádza článok s názvom "U.S. life expectancy hit an all-time high in 2024, CDC says". Available data from the CDC shows that life expectancy in the US will reach 78.4 years in 2023[2], an increase of 0.9 years from 2022[2]. In 2023, the average life expectancy for men was 75.8 years and for women 81.1 years[2]. Data for the year 2024 is not available in the provided search results.
