Carpe Diem!
Seize the day!

Carpe Carne!
Seize the meat!

The brevity of life is somewhat enigmatically pointed at, in similar fashion, in the Jewish-Christian apocryphal Book of Esdras.  The prophet, watching under the oak-tree for his revelation, has a vision of the Lord: ‘Behold, he reached me a full cup, which was full as it were with water, but the color of it was like fire:  and I took it and drank: and when I had drunk of it, my heart uttered understanding, and wisdom grew in my breast.’
Another passage likewise alludes:
‘On  the world’s coquetry, fools, lavish not your coin,
When all her ways and windings know ye, line by line;
Give not unto the wind this precious life, your own,
But hasten, seek the Friend, and quickly quaff the Wine.’
