They are going to be fantastic at anything with high level requirements on finger and limb placement, providing they also have the other required characteristics needed for the activity or skill.
This can include careers like surgeons, acrobatic performers, and bomb squad diffusers. A steady hand or foot with the exact right placement will serve them well.
They will be good at mountain climbing, playing piano, drums, accordions, and saxophones (most instruments, really) , and knitting and crocheting.
They will have a higher strike percentage in bowling, and and an almost uncanny knack at acing the 7 - 10 split because once they figure it out, they know exactly the right limb placement and twist of the wrist to use and where in the swing to release the ball.
All the performance dances will be easier for them, including ballet, the Flamenco, and especially break dancing.
If they are athletically inclined, any sport they pursue will benefit from this heightened sense...tennis, slalom skiing, snowboarding, and basketball to name only a few. Anything involving aerial body positioning and balance would be good too: high diving, ski jumping, and any gymnastics event.
Home activity benefits:
Things like balancing on precarious perches and ladder work to reach high places when hanging items or cleaning will be easy. They will save on energy as lighting will be less critical for many tasks--they know very well how many steps and at which angle the trash bin is at.
Those are good examples of the physical traits.
Some emotional and social traits involving the high empathy could show up in less obvious ways.
Depending on their base personality, they might be the one everyone goes to for hashing out their issues because they are always so understanding. They seem to get the problem quickly and sense when the person talking to them needs to just vent versus when they truly need advice.
The empath will be good judges of group moods and steer clear of events they don't want to or can't participate in at the time. Having the empath in a group could backfire for folks that are stirring up trouble on the sidelines because the empath is going to see that body language from a mile away and, in recognizing it, simply choose not to respond at all to remove themselves from inappropriate drama before it gets too close.
In situations where they can't understand what a person is saying but are able to view them in person, they will judge the importance of the topic based on their empathic skills, and the majority of the time will correctly guess an appropriate comment or body language to present back without the other party knowing they had no clue what was said. This can back fire on them in ways that vary from harmless--friends giving them a hard time about catching them doing it--to catastrophic--losing a very good friend because of the rare time they guessed wrong at the worst moment and didn't realize it in time.
Due to large group dynamics where there might be too many conflicting, high level emotions abounding, the empath could eventually learn to dial back the ability, find ways to dampen it, or tune it out out altogether. If they do not learn to do that, they could become reclusive. It could be that even when able to control the ability, since doing that can cost energy and effort, they will seclude themselves from social events periodically just for needed rest that others may not need nor understand.
