One of the problems with being 40, fat and faithful (well, trying to be anyway) is that it gets more and more difficult to meet non-Christians.
I work in a Christian company, my old friends have either been converted, or scared off, and middle age brings with it an upsurge in responsibilities at church which seem to dominate our social life.
My wife is luckier. Having two newish children means that she gets to meet and spend time with lots of non-Christian women: the post-natal group, various creches and playgroups and at the school gate. But when I'm not locked up at work, I'm either feeding, bathing, playing with the kids or putting them to bed, and then settling into a routine of housegroup, Bible study or talk preparation, solo relaxation (I'm reading the excellent seafaring stories of Patrick O'Brien at the moment), or sleeping.
