  We present 3D full star simulations, reaching up to 90% of the total stellar
radius, for three $7M_\odot$ stars of different ages (ZAMS, midMS and TAMS). A
comparison with several theoretical prescriptions shows the generation spectra
for all three ages are dominated by convective plumes. Two distinct
overshooting layers are observed, with most plumes stopped within the layer
situated directly above the convective boundary (CB); overshooting to the
second, deeper layer becomes increasingly more infrequent with stellar age.
Internal gravity wave (IGW) propagation is significantly impacted in the midMS
and TAMS models as a result of some IGWs getting trapped within their
Brunt-V\"{a}is\"{a}l\"{a} frequency spikes. A fundamental change in the wave
structure across radius is also observed, driven by the effect of density
stratification on IGW propagation causing waves to become evanescent within the
radiative zone, with older stars being affected more strongly. We find that the
steepness of the frequency spectrum at the surface increases from ZAMS to the
older models, with older stars also showing more modes in their spectra.
