Agar kisi ka mercury 1,5,9 hai I will say inki commition to achi hogi but ye log aapni intelligence se logo ki problem bhi solve kr sakte hai 

But agar mercury acha house rashi  meh nhi hai to or ache se placed nhi to insaan problems create krne lagta hai jo hai bhi nhi or unko solve krne ki koshish krta hai jo problem exists he nhi krti  for example:-

What will I do if this happens with me, what if someone attacked me , I think I have this health problem etc 

And agar mercury krab hoga to  bua se sister na bani , nervous problem rehna , ye sab dekhne ko mil sakta hai 

Or insaan enjoy bhi nhi krta aapni zindagi ko
