Czterdziestolatek or 40-latek (; transmitted by TVP Polonia as ) was a Polish television comedy series broadcast between 1974 and 1977. The first series enjoyed so much popularity that it continued and led to the release of a feature film I'm a Butterfly, a 40-year-old Love Affair and a New Year's Eve television program in 1975.
The series was written by Jerzy Gruza and Krzysztof Teodor Toeplitz and was broadcast on Telewizja Polska. In total, 21 episodes were produced.
The series followed the fate of a Warsaw family and explored topics related to midlife crisis, such as extra-marital affairs, attempts to quit smoking, obsession with hair loss, efforts to maintain physical fitness, pride in achievements and professional life, the desire to seek self-fulfillment through social activities, etc.
20 years later the series was remade in the mid-1990s with a cast that included Joanna Kurowska, Wojciech Mann and Wojciech Malajkat.
