Perfect health, forever young...why not? Isaiah describes paradise conditions further in Isaiah 65...
21 They will build houses and live in them,
+
And they will plant vineyards and eat their fruitage.
+
22 They will not build for someone else to inhabit,
Nor will they plant for others to eat.
For the days of my people will be like the days of a tree,
+
And the work of their hands my chosen ones will enjoy to the full.
23 They will not toil
* for nothing,
*+
Nor will they bear children for distress,
Because they are the offspring
* made up of those blessed by Jehovah,
+
And their descendants with them.
+
24 Even before they call out, I will answer;
While they are yet speaking, I will hear.
25 The wolf and the lamb will feed together,
The lion will eat straw just like the bull,
+
And the serpent’s food will be dust.
They will do no harm nor cause any ruin in all my holy mountain,”
+ says Jehovah.
And Micah 4...
3 He will render judgment among many peoples
+
And set matters straight
* respecting mighty nations far away.
They will beat their swords into plowshares
And their spears into pruning shears.
+
Nation will not lift up sword against nation,
Nor will they learn war anymore.
+
4 They will sit,
* each one under his vine and under his fig tree,
+
And no one will make them afraid,
+
For the mouth of Jehovah of armies has spoken.
