Exercise is the key not only to physical health but to peace of mind.

Leaders will have to give clear and decisive leadership towards a world of tolerance and respect for difference, and an uncompromising commitment to peaceful solutions of conflicts and disputes.

I have retired, but if there's anything that would kill me it is to wake up in the morning not knowing what to do.

I have always endeavoured to listen to what each and every person in a discussion had to say before venturing my own opinion.
