Philosopher Nick Riggle explores the beauty of being alive by investigating the things we say to inspire ourselves and each other: seize the day, you only live once. These clichés imply that you should do something wild with your life because it is precious, a little like saying you should go swimming with your grandfather's watch because it is irreplaceable. Drawing on?his experiences as a new father,?Riggle shows us that life is beautiful enough to bear repeating.
