An 80-year-old Constantine woman will be jumping out of a plane to raise money for charity in memory of her late son.

Pensioner Val Bruce is undertaking the daring skydive along with her 18-year-old grandson Max to raise funds for MS Research on July 7, the day that her son Alex would have turned 55.

Val said: "I have avoided doing anything dangerous my entire 80 years. I'm actually quite nervous of heights and don't like looking over cliffs or anything. It's madness, I know, but I just thought it was something meaningful I could do."

Alex passed away in February 2005 at the age of 41, just three years after he was diagnosed with secondary MS. He left behind two young daughters, Tegan and Leah, and his wife Jacki.

Val said: "I hope to be able to donate a truly worthwhile sum of money to further MS research as it means so much to me and I feel research into this illness that causes so much heartbreak, pain and loss is vital."

Val and Max's tandem jumps will be done in Perranporth, with the money raised being split between MS Research in the UK and Australia (where her son lived).

The 80-year-old daredevil was inspired by her Australian friend Carol Langford, whose work for MS Research following the death of her daughter led her to be named Australian Woman of the Year in 2009. She also has in mind Alex's childhood friend Alastair and his godmother, who both have the same type of MS that he did.

Val said: "My daughter wanted to organise a party for me, and I just thought I wanted to do something that was more significant than a knees-up.

"I know if I don't do anything now, I'll probably never do it."
