alternating days and nights

temperatures follow the seasons

financial markets go up and down

housing markets boom and crash

the popularity of movie stars explodes then fades away

sports teams rise to ascendancy then slip back into oblivion

a new restaurant attracts crowds 

but over time empty tables appear

political leaders are initially adored 

their ratings inevitably fall with time

babies need caring for as they develop

growing into adults who care for their own babies

then they get old and need to be cared for again

nothing is constant

atoms from dead stars make up the cells in living organisms

the cells in your body die off daily

replaced by new ones

over time the replacement cells are less reliable

ultimately leading to death

but the cycle continues

the atoms from dead plants and animals get recycled

new life begins again with atoms from dead stars

stars in the sky burn bright but eventually burn out

our ever-expanding universe will one day go dark again

it will shrink back to nothing

before another big bang creates a new expanding universe

everything follows a cycle

enjoy the ride

while it lasts
