I had no clue what to expect from the science exchange, and I filled out my form having just watched the documentary "Bad Blood" about HIV infected blood in the donor blood supply, and the devastating effect it had on haemophiliacs, and I spoke about it a lot on my form.

My santa went off this and gave a very kind donation of £25 to The Terrence Higgins Trust, who are working to combat prejudice against HIV positive individuals.

I feel what they are doing is very important work, so am really very touched by this fantastic gift - YOU ARE AWESOME SANTA!
