When I was 23, 6'2', 160 lbs, and nothing hurt, ever, I owned a 69 RHD PI for a short period while stationed at RAF Lakenheath in the UK. Then Jennifer was born and the 69 was gone. I was 23 when my 75 was conceived. I was 51, 6'2', 210 lbs, and everything hurt almost always, Jennifer was 28, when the 75 was acquired.
