What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.
Do it no matter what. If you believe in it it is something very honorable. If somebody around you or your family does not understand it then that's their problem. But if you do have a passion an honest passion just do it.
