Because I can.
I went to my Doctor the other day (for the first time in about six years) to talk to him about my knee.
Before the visit, I confidently predicted that he'd instruct me to lose weight. While I was there he asked me what my height (1.78m) and weight (117Kg) were, which he typed into his little computer, and he measured my blood pressure (120/80 mmHg) which he said was "excellent". And he didn't tell me to lose weight at all.
Hence the croissants and apple turnovers.
(I've had an X-ray of the knee, and we talk again next week sometime)
