You might not smell as bad because you never made an antibacterial nest in your armpit where just whatever can grow once it’s gone, instead it being filled with your natural flora, but that does not change that you have more body odor than those around you (for both good and ill)










Speed isn’t the factor being multiplied here, it’s fuel efficiency. It would be much faster to give the probes enough delta-v to handle flying straight (via a parabola) to their ultimate destination then to bother wasting time with gravitational assists. But the cost in fuel would be astronomical. Literally, even.
