This body may be younger, but it often feels like driving a clunky rental. Catriona’s strength isn’t the kind I’m accustomed to. Legs that are used to standing all day, yet balk at moving faster than a walk. Arms that can hoist a full water bucket, yet ache after an hour wielding a pen. And don’t even get me started on my core. Remove the corset, and I can barely manage a proper sit-up.
