as Mars rules the 7th house and Mars is placed in the 12th house, his spouse should be quite spendthrift and do wasteful expenses. She will be active, energetic, independent views, courageous but moody and stubborn at times. As 7th lord is in the 12th house cojoined with Rahu in Aries its own rashi she will have low immunity and get sick easily. Should see while doing the horoscope matching that the girls horoscope indicate good health.
