Most often inductors are used to block AC or high frequency signals. This is the dual of what capacitors do which is pass AC or high frequency signals. The precise definition of what is high frequency is a bit loose and depends on the circuit values.
I am 50 and have been in menopause for about 14 months. Since April of last year, I have experienced periods of INTENSE hot flashes and night sweats - sometimes 30 within 24 hours! These periods last 6-8 weeks and then the hot flashes reduce in intensity and occurance gradually over the next 10 weeks. Then, unfortunately, they start again.
I'm 47. My last period was 8 months ago. It lasted about 3 weeks, stopped for a week, and then I had another one which lasted a week. Nothing since then, and the hot flashes have all but stopped.
