Latin... a dead language? Doesn't seem like it to me!

Found this somewhere... and thought it was brilliant!

Vivamus, mea Lesbia, atque amemus,
rumoresque senum severiorum
omnes unius aestimemus assis!
soles occidere et redire possunt;
nobis cum semel occidit brevis lux,
nox est perpetua una dormienda.
da mi basia mille, deinde centum,
dein mille altera, dein secunda centum,
deinde usque altera mille, deinde centum;
dein, cum milia multa fecerimus,
conturbabimus illa, ne sciamus,
aut ne quis malus invidere possit
cum tantum sciat esse basiorum.

Let us live, my Lesbia, and love.
As for all the rumors of those stern old men,
Let us value them at a mere penny.

Suns may set and yet rise again, but
Us, with our brief light, can set but once.
The night which falls is one never-ending sleep.

Give me a thousand kisses, then a hundred.
Then, another thousand, and a second hundred.
Then, yet another thousand, and a hundred.

Then, when we have counted up many thousands,
Let us shake the abacus[3], so that no one may know the number,
And become jealous when they see
How many kisses we have shared.
