I will discuss Effective Field Theories that can originate from microscopic unitary theories, and their relation to moment theory. I will discuss the implications for pion physics, as well as showing that massive gravity, theories with isolated massive higher-spin particles, and theories with very irrelevant interactions, don't posses healthy UV completions. .
