Why did howard hughes grow his hair and beard?

He joined the anti-MAD vs MAD-anti-nuclear war movement and owned more land than anyone in atomic city Vegas Nevada where he was alo the largest employer in the state.He went hippy generation anti-war like millions of Americans did and he helped to slow the atomic clock that was near midnight(CUBAN/RUSSIAN) missiles 200 miles offshore from America.He was labelled as crazy by pro-war Hollywood and pro-war government and his wealth was stripped away and he left the country.
