I started to read John Kavanagh's Win or Learn: MMA, Conor McGregor and Me: A Trainer's Journey on the recline bike lunchtime today. (Three titles for one book! Never mind the quality, feel the width.)
That means it took me from June 6 (Icons passim) until last week to finish The Gene: An Intimate History. I know it weighs in at 608 pages but I used to get through a book every week or so; two months seems a touch offhand.
