Of course Arnold isnt as big as in his prime, since he is much older now, but he's had a wonderful ride and a great career during the years.
Both Lou and Ralf will shrink with age, we all do.
We begin as nothing, then a mere thought, start life in diapers and end it the same way before disappearing to nothingness, and all that remains is the thought of the person.
Legends such as Arnold, Bruce Lee et al, will still be remembered many years after their passing.
