From what I have seen in life, it is very common for some people to sense from a distance, but it never happens for other people. In elementary school we played with seeing who could feel someone else staring at them. Some of the kids had said that it was impossible to feel someone staring at you 'because science said so', but we proved them wrong (grin).
We also had other 'games' that tested people's sensitivities; it was a lot of fun while showing us that there are huge differences between different people.
A fun example was of my sensing an online friend writing an email to me (I felt and knew that he was thinking about me (we shared emails about a research topic)), but I never received the email. For about a week I was super antsy because I could sense his thoughts towards me. When the email did arrive, the friend explained that he had written the email a week previously, but hesitated sending it as he continued to reread it and make corrections. The friend lived in Canada, while I was living over 2,000 miles away in southern USA.
In the country, one example was of my smelling and sensing two people driving past my land about 500 yards away. Though the strong wind was from behind me, I could sense their general ages, foods eaten, and many more details, all of which were proven correct when I walked to their car. My wife and I both would feel people exiting the highway about a mile away, who were to drive to our gate. It gave us time to leave the house and walk to the gate before the intruders could trespass.
Distance of perception is irrelevant.
In my younger days (before having a neck injury) I could sense a lot of things that most people cannot sense, but today I almost never feel someone thinking about me (which is okay because at this point in life I am enjoying being a nobody!).
I can still sense the people I like at a distance, and what they are doing, and too, I can sense when my wife has decided to walk across the house to talk to me. As I mentioned on another post, when I feel the time is right, I walk to talk to my wife as her DVD movie is ending within about a minute (sometimes at the last seconds of credits).
But for other people, I really don't give a focused effort to sense them.
A related topic is that I often 'reach out' to sense people's activity at stores, so that I will know if the trip will be fast and easy or slow and frustrating. A fun recent example was sensing that I should leave at a specific time; I drove to the store, getting the green light at all four busy intersections (never happened before), got on and off the highway without stress, made the 5 mile trip in record time, and the store did not have any customers inside when I arrived.
Most everyone I have talked to has incorrectly said that the perceptions are paranormal and psychic. I will purposefully avoid speaking of the method, but it is sufficient enough to say that everyone on earth has different sensitivities of sensory perceptions, including sight, hearing, smelling, tasting, and feeling.
Years back I mentioned in a forum that I could see many more colors than what science claimed was possible, and the forum people responded very rudely to me. A couple years later, science 'discovered' that some people really do see more colors than what was previously believed, and science gave it the name 'tetrachromacy'. Scientists still do not understand how tetrachromacy works, and as long as we never make the information public, science never will know.
Sensing from a distance is extraordinarily common throughout the world, but science does not know anything about perceptions, and for as long as we do not make the information public, science will not be able to copy-paste-plagiarize a new 'discovery'.
Your lower left back location of sensing other people is likely uncommon, but I remember someone else speaking years ago of a similar location. Too, there have been reports of the USA government having tested people who sense from distances, so again, sensing other people is not something new.
When you marry and have a close relationship, you might find your sensations increase to the point of knowing more details of distant people, and that might also be when you decide that there are some things that you do not want to sense (grant the people privacy).
