When I was a kid there was no such thing as sunscreen. I just had a few of my many keratoses, [flat bumps that resemble warts] which had gotten a little dark and suspicious looking, zapped with liquid nitrogen. The dermatologist said in 8 or 10 years they’d likely become cancerous. Take are of yourselves. My generation couldn’t.
I have measured the deformation of steel under light loading. The deformation under such very light loading as a fly would be very small and hard to measure. I also did not say or imply that the deformation would be permanent. A more descriptive word might have been ‘flex’.
If a fly lands on a steel girder it bends from the extra weight. Not much, but it does bend. Setting off a small rocket repeatedly during a time slot where it points behind the Earth as it orbits the Sun would raise the orbit, by simple orbital mechanics. [Just not very much. ] Check out apogee and perigee.
Smoking is part of what killed my father. Never was interested in trying it. Every morning I heard “hack, cough, gag, spit … repeat”
