Setting mempool expiration period on my node

[junghyun0783]

Is it possible to set the transaction expiration period of the mempool on the node I am operating?
It is said that it is possible to set it with Chat GPT.
"ex) geth --txpool.lifetime 24h"
If I set the transaction expiration period like this,
Will the pending transaction be removed from the mempool after 24 hours?

I will wait for the experts' answers.
Thank you.
