Kant was only 5 feet tall, thin and of fragile health. Nevertheless, he reached at the time extremely old age which he attributed to his strict daily routine. He got up at 5 o’clock every day and spent the next hour drinking tea, smoking his pipe and meditating. From 6 to 7 o’clock, he prepared for lectures he gave at home until 9 o’clock. He then worked in his study room until 1 o’clock and spent the next three hours dining, usually with his friends. After his only meal, he took a one hour walk and spent the afternoon and evening for reading and writing. The renowned German philosopher was completely dedicated to his work and never married.
