The leading men of the 1930s and '40s look so much more mature and "lived in" than today's crop of younger stars… It was 99% the result of their lifestyle. Humphrey Bogart famously never worked out, and he hated it — he felt it was unmasculine to go to the gym. He consumed each day only the following: French toast, several Scotch and sodas, an omelette, milk, coffee, countless cigarettes and cigars and a glass of brandy before bed. Despite Bogart’s not very healthy lifestyle, he weighed no more than 150 pounds for most of his adult life, which is a decent weight for a man who stood 5′8″. The “macho image”, in Bogart’s mind, was primarily the result of a man’s aura, a man’s vibe, a man’s posture and body language. You had to carry yourself a certain way, talk a certain way, address the world and all that’s in it as a real man, and you’d be perceived as such. Rippling muscles and chiseled abs weren’t necessary, you just needed to be a man’s man and live life accordingly. The leading men of Old Hollywood drank heavily, smoked like chimneys and most of them never saw the inside of a gym — it was the stuntmen who worked out and had the type of muscles today’s Marvel superheroes carry. The average leading man was a man selected primarily for his persona and the way he carried himself. He had to say the lines well and make you believe he was the hero, the tough guy. They aged prematurely, and often died young.
