I believe there are two important inventions of my life time. One being the Automated Teller Machine (ATM). The freedom to get money out of your banking account any time you want has been a great convenience. Introduced by John Shepherd-Barron.
The other important inventions is the heart transplant. Invented by Dr Robert Jarvik a massive milestone in medical science. It has saved many lives since it was invented.
