We show that for dimensions which may be much larger than k(K), the upper inclusion in Dvoretzky Theorem (3) holds with high probability. This reveals an intriguing point in Dvoretzky Theorem. Milman’s proof of Dvoretzky Theorem focuses on the left-most inclusion in (3). how fast does a dog\u0027s heart beat
