  At age two, humans are just learning to speak, and they see the world in an
unbiased way. At age two, the COMPLETE (COordinated Molecular Probe Line
Extinction Thermal Emission) Survey of Star-Forming Regions is just beginning
to hint at what it will do for our world view, and it is unbiased as well. The
coordinated observations that comprise COMPLETE have already shown us: 1) that
large (~10pc) scale bubbles created by winds from evolved stars dominate maps
of extended dust emission even in relatively low-mass star-forming regions
(e.g. Perseus and Ophiuchus); 2) that "giant" (>1 pc-scale) outflows from young
stars can be easily detected by applying statistical tools to an unbiased CO
survey (e.g. we have doubled the number of known outflows in Perseus using the
Spectral Correlation Function); and 3) that many apparent high column-density
"clouds" seen in projection are actually the superposition of many velocity
features (likely at different distances) along the line of sight. The upcoming
detailed analysis of these new observations will quantify the degree to which
the apparently ubiquitous spherical and collimated outflows can sculpt and stir
molecular clouds. Taken together with recent numerical simulations' results and
measurements of high velocities for some young stars, the COMPLETE Survey also
raises, and should soon answer, questions about how, when, and how far stars
move away from their birthplaces as functions of time.
