Let's make this birthday one to remember.

74 years old (Born on October 01, 1950)

Happy Birthday, Boris!

Celebrating the man who took the term "house call" to cosmic heights—literally! Your stint as mission specialist aboard NASA's Space Shuttle Atlantis in 2000 proved that you truly give an out-of-this-world check-up. Anyone who's operated medical equipment hundreds of miles above Earth clearly deserves extra cake today.

On this special occasion, we're reminded that gravity could never weigh down your achievements. From safeguarding astronaut health to inspiring future space medics worldwide, you've proven there's no limit—even beyond Earth's atmosphere—to what one dedicated doctor can accomplish.

Here's hoping your birthday blasts off into legendary fun!
