Aviation Aerospace Australia has produced an amazing Video Here to show girls what careers are available in the aviation and aerospace industries. Mathspig has met 3 female Boeing Engineers and a female engineer that worked on the Williams Formula 1 car.
An information brochure (link below) that goes with the video gives subject advice and income ranges over a lifetime career:
Meanwhile, this is why girls (and boys) should do STEM.

The minimum wage in Australia is currently $19.84 per hour for 21yo+. This is USA $15.08.

The Australian Open is on at the moment in Melbourne in LOCKDOWN. (We have 1 community-acquired case. Tennis players are in a bubble.)
Here are the heights of 3 top seeds in the Australian Open. (See graph below)
No. 1 Novak Djokovic 6ft 1″ (73 in)
No. 6 Alexander Zverev 6ft 6’ (78 in)
No. 8 Diego Schwartzman 5ft 7’ (67 in)
That would be an advantage. Here is a Height vs Serve Speed chart for the Top 6 seeds in the tournament:
Find serve speed data here.
There is NO CLEAR HEIGHT ADVANTAGE for serve speed.
Here is Diego Schwartzman (L) when he defeated Alexander Zverev (R ) in the 2019 US Open.
Schwartzman, the shortest player on the circuit (see graph above), tops the service returns stats. Highest 2nd serve return rate. Third highest 1st serve return rate. See data below. So agility, speed, and reaction times are also important factors in becoming a tennis star.
Go Schwartzee! Check data here.
