If You Could Travel to Any Time Period, When Would It Be?

I will travel to Ancient Greece during the 5th century BCE. I will learn from pioneers like Pythagoras, Empedocles. What about Socrates, Plato and Aristotle, these are the men I will love to see and engage with them.
 
2000 years in the future lol. Maybe they invented something by then to stay young/healthy forever.
 
If I had to choose, I’ll go for the Renaissance era, specifically the Florence in the 15th century. This when they experience explosion in art and innovation
