Anyone interested in this topic either from current performance levels or anticipated future performance levels might well want to watch this video. This is Dr Ken Berry, a family GP in the USA but if you cast your net widely then you will find other sources that concur. You might, as you scurry around looking for contradictory sources, find material that conflicts but that is understandable under the current climate. Worth a listen for anyone who wants to enjoy their younger Filipino partner going forward.
Don’t take my word for it, or even Ken Berry’s. How about this guy. Stand to attention (guffaw guffaw) and listen. It may just save your marriage…..
