Restricting mTOR activation upregulates cellular maintenance and repair processes, which is beneficial in a modern environment with mutagenic influences.

“when you do restrict mtor what you are doing instead of making new cells which is an expensive thing to do and a potentially risky thing to do particularly in the modern world in which we live where we're surrounded by so many in a toxic mutagenic influences um that what we want to do when you when you restrict mtor what you're actually up regulating instead is maintenance and repair”
