Why might have Plato never traveled to India, if he must have been aware of much knowledge coming from there?

One pre-Socratic Greek who did visit India is Scylax: http://en.wikipedia.org/wiki/Scylax_of_Caryanda

Plato probably received some knowledge of Indian thinking via Egypt; however, the reputation of Indian thinking was not particularly awesome.

Indian thinking becomes more influential in the 3rd century BC, by virtue of the Buddhist emperor Ashoka sending Buddhist teachers to the Hellenistic area to promote the "Law of Piety."

"Long Pilgrimage," John Bennett.

The 9:12 to new Delhi was already booked the day Plato decided to make a trip.

Nobody in Plato's era and of his notoriety could have travelled to India and his contemporaries wouldn't have known and written about it. India was known to the Greeks.

Whenever he planned a visit to India, there was some or the other impediments, hurdle or obstacle. Hence he could not make a visit to India.

Why might anybody not go somewhere? Too poor? Too old? Bad health? Fear? Political reasons? Could be many reasons.

Disneyland New Delhi hadn't opened then.
