I live on my own at the mo, as my OH hasn't relocated here yet.
Told a few of friends who are doing or have done similar.
My OH got informed.
Family don't know, and won't until it becomes an issue for catering purposes.
Work don't know, none of their business.
People will start to notice eventually and ask questions, by which time I may well 'come out'. A friend who did LL, when told it was unhealthy usually replied with 'Do I look unhealthy??', which generally works...
