Question

My life can be measured in hours, I serve by being devoured. Thin, I am quick. Fat, I am slow. The wind is my foe. What am I?

Answer 1

CANDLE

The answer to the riddle is, "A candle." A candle's life is 'measured in hours', as people only care about how long its flame will last. When you light a candle, it starts to melt, therefore it 'serves by being devoured'. A thin candle will melt quickly while a fat/large candle will burn for much longer.

Answer 2

candle. the more it burns the faster it dies. if it's thin it burns quicker, if it's thick it burns slower
